# 3.1. Queries Queries are a powerful tool the Officers can use to filter occurrences, validated reports and original reports through various stages in the E2. Also, safety recommendations should be made if the officer belongs to a Safety Investigation Authority. [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/t7Zimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/t7Zimage.png) ### 3.1.1. Queries overview and Libraries tree view In the Queries section, the Administrator can create queries, share them with other users or manage queries shared by other users with the Administrator. The Administrator has to open the 'Data Management’ menu at the top of the page, then click on the 'Queries' option (Data Management > Queries). The system will display the Queries menu: [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/3Xzimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/3Xzimage.png) On the left panel, there is a view of the Libraries tree. It includes all the libraries available to the Administrator. Those are the folders that can have categories and subcategories. Find more information about these libraries in the [Libraries](#_Libraries) section. The libraries available to the Administrator are: My Personal Libraries, the Local Common Library, the Common BO Library, the National Shared Library, and the Shared with Me Library. Administrators can click on the corresponding libraries, and the content will be displayed in the queries overview in the right panel. On the Queries menu, Administrators will have all the folders available, but only the queries will be accessible to them, although the Libraries tree view is the same. On the right, there will be the list of default Queries. It shows the first Library with the content of the Tree view, as seen in the image above. The list shows the corresponding folder or category of the library and below its subcategories if existing, and the queries. The columns that also work as filters are the following: · **Name**: It shows the category, its subcategories, and the queries if they exist. Administrators can unfold the folders through the arrows. · **The ‘BO’ column shows a green tick if the query** is used in a batch operation. N/A for SRIS queries for the moment. · **Author**: it is the username of the author of the query · **Date**: Creation date. · **‘To Lobby’** column shows a green tick if the query can be exported to another environment and a red cross if it cannot be exported to another environment because it contains Custom Attributes. ### 3.1.2. Query builder - creation of a query The Administrator can create queries in My Personal Libraries and the Local Common Library. The Administrator must click the 'New Query' button to create a new one in the selected library or folder. (This New Query button is unavailable when navigating through ‘Shared with me Libraries’ and ‘Lobby Libraries, whose queries can be executed and copied by Administrators but neither created nor edited nor deleted.) A new window will be displayed with the Query Builder: [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/RnFimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/RnFimage.png) The Query Builder allows the Administrator to build queries to search original reports, validated reports, and occurrences or safety recommendations, depending on whether the Administrator’s Authority is a National Aviation Authority, a Safety Investigation Authority or both, with Attributes or metadata fields that meet the given conditions. The queries are executed against the reports indexed in Elastic Search. The Administrator has to fill in the unique Query Name for each Administrator query and select a Library, category or subcategory where to store the query. See the Libraries section for more information. Before executing, exporting or saving a query from the query builder, it is required to select over which reports the query will be executed on the ‘Count Number of Items’ section: **ECCAIRS queries (based on ECCAIRS Taxonomy)** They will be activated as soon as the mandatory fields of the query are filled. · Original Reports · Validated Reports · Occurrences · Occurrence shared with me: Occurrences shared by other Authorities with my Authority. · Occurrence + Shared: My major occurrences and the ones shared by other Authorities with my Authority · ECR: All occurrences shared with the ECR by my own and other Authorities. **SRIS queries (based on SRIS Taxonomy)** They will be activated as soon as the mandatory fields of the query are filled. · Safety Recommendations · ECR: All safety recommendations shared with the ECR by mine and other Authorities. ### 3.1.3. Query conditions – Attributes and metadata Once in the Query Builder, the Administrator has to select the query parameters to set each rule by clicking on ‘Select Attribute’ under the ‘Conditions’ section.

Query structure The queries are made at least by one rule in a group. A rule is a condition the search made by the query has to meet. Queries can also include various rules and or groups of rules. A query can include one or more existing queries (subqueries). A rule contains a condition to be met concerning an Attribute or metadata field. Layouts and operators vary depending on the Attribute and metadata field type, i.e.: If the Administrator selects Air temperature as an Attribute, the system will display ‘Value’ as the only possible selectable layout and the Select operator filter: [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/RQfimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/RQfimage.png) This will also generate a ‘Decimals’ field to be filled out by the Administrator. **Attributes** · **Alphanumeric** and **Text** Attributes or metadata fields can be searched in documents by a complete word using the layout ‘Value (Word)’ or by a string of characters using the layout ‘Text’. i.e.: ü Value (Word) as in ‘Aircraft’ (complete word) ü Text begins with ‘Airc’ (a string of characters)

Groups can include one or more rules and one or more groups combined with AND/OR clauses. The Administrator must click the ‘Add Rule’ button to add more rules. For groups, on the ‘Group’ tab. If the Administrator wants different sets of rules to be evaluated together, the Administrator must click the 'Add group' button. The Administrator can also add groups to other groups. Groups and rules can be rearranged, dragging and dropping them where needed. At the top centre of each group are the OCCURRENCE/ENTITY alternative tabs, which show whether conditions of the given Attributes shall be met in any instance of the Entity or if the conditions shall be met in the same instance of the Entity. Thus, when specifying restrictions in a query, the restrictions can be evaluated across all the entities of a record at once OR can be assessed to each Entity of a record one by one. By default, the restrictions of a query will be evaluated across all the entities of a record at once, with the 'Occurrence' option selected by default. With the selector 'Occurrence/Entity', the Administrator can change that, and the restrictions will be evaluated Entity by Entity. There is a limitation in creating groups based on the restriction selected here. If a group is restricted to Entity, no more groups can be added inside that "Entity" group. Example of search by occurrence and by Entity: 1. **OCCURRENCE**: If we want to obtain the Occurrences where the Manufacturer model (21) is equal to ‘BOEING > 787’ and the Aircraft altitude (22) is greater than 1000 ft, independently if the conditions are met **in different aircraft of an occurrence**: [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/tDGFGiimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/tDGFGiimage.png) 2. **ENTITY**: If we want to obtain the Occurrences where the Manufacturer model (21) is equal to ‘BOEING > 787’ and the Aircraft altitude (22) is greater than 1000 ft when the conditions are met in the **same aircraft**. [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/FYKimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/FYKimage.png) The Administrator can set rules with AND/OR clauses and combine them as needed with groups by clicking on the ‘Group tab’ and selecting AND/OR clauses, i.e.: [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/kHVimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/kHVimage.png) **Subqueries**: The Administrator can add a subquery to the query through the ‘Query’ tab. The aim is to add an existing query available for the Administrator to the current query. When the Administrator clicks on the ‘Query’ tab, the system will display the subquery section: [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/qmFimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/qmFimage.png) The Administrator has to click on ‘Select Query’, and the system will display a window to select the subquery:[![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/GaZimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/GaZimage.png) The Administrator must select a query from the available libraries and click ‘Add’. The system will add the subquery to the conditions of the current query. ### 3.1.5. Query action buttons Once the query is completed, the following options are available: · **Cancel** button: the system will return to the Queries page. · **Execute** button: N/A to the Administrator unless they have the Officer’s role. · **Save** button: The system will save the query in the list of queries of the selected library and display the table of queries with the new query on the queries page. · **Export** button: N/A to the Administrators unless they have the Officer’s role. ### 3.1.6. Query Management The Queries menu displays the table of queries of the corresponding Library, category or subcategory selected in the Libraries tree: [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/V78image.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/V78image.png) #### 3.1.6.1. Editing a query Only Queries of ‘My Personal Libraries’ and ‘the Local Common library’ are editable for the Administrator. If a query is associated with a BO or query-based notification, it is not editable. In those cases, the query is visible through the ‘View button’ of the 3-dot menu or by double-clicking on the query on the table of queries. The Administrator has to double-click on the specific editable query of the queries list or click on the ‘Edit’ option of the query’s 3-dot menu, and the system will display the editing page of the query: [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/Uzpimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/Uzpimage.png) The Administrator must introduce the needed update and click ‘Save’. See Query action buttons for further details. This page also provides: · **Elastic Query viewer** button: it accesses the Elastic Query Viewer window as follows, [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/S1Aimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/S1Aimage.png) · **Query viewer** button: it opens the query viewer window as follows, [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/e29image.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/e29image.png) #### 3.1.6.2. Duplicating a query All queries available to the Administrator, no matter the library or category, can be duplicated by the Administrator. The Administrator has to click on the copy icon of the 3-dot menu of the specific query of the list of queries, and the system will display the ‘Copy Query’ window: [![image.png](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/scaled-1680-/FwZimage.png)](https://help.ci-aviationreporting.eu/uploads/images/gallery/2025-11/FwZimage.png) It is like the editing page above but with the mandatory Library field empty. The Administrator has to fill in the Library field with a different Library than the original one, and then the Execute and Export button will be activated. The Save button does not work unless a Library is selected. The Administrator must introduce the needed update and click ‘Save’. See the Query action buttons section for further details. #### 3.1.6.3. Sharing a query The Administrator can only share queries of ‘My Personal Libraries’. Only the queries not involved in a batch operation or a query-based notification can be shared.
