# Expert Search The **expert search** provides full control over your search by giving access to **all enabled fields**. It allows you to define precise search criteria for each field, making it possible to locate records based on very specific combinations of data. This feature is designed for advanced users who need more granular control than the standard search or filters provide. Once you have defined your search criteria and applied the expert search, the system converts your selections into **search tokens** that are added to the **full-text search**. These tokens function just like any other search term, allowing you to combine them with additional full-text search queries. After applying the expert search, you can **reopen the popover at any time** to add more fields. This flexibility enables iterative searching and fine-tuning of your results without starting over. ## Field Options ### All Fields For every field in the Expert Search, you can choose to search for records that **have data** in the field or that **have no data**. This makes it possible to include or exclude records based on whether a particular field is populated. ### Hierarchical Lists For hierarchical lists, you can choose whether you only want results that match the selected entry, or those who are connected to the subordinate entries. By default, subordinate entries are included. To only search for records that reference the chosen entry, disable the checkbox next to the field. ### Date Fields **Date fields** are always displayed as a **date range**, allowing you to search for records within a specific range of dates. To search for a single, specific date, you must enter the same value in both the **"From"** and **"To"** fields. If only one field is filled, the search will perform an **open-ended range**, returning either all records **older than** or **newer than** the entered date, depending on which field is specified. In addition, you can switch to **more options** to select **relative dates**, such as **"Today"**, **"In 7 days"**, or define a **custom relative range**. This feature enables quick filtering based on dynamic time frames without manually entering exact dates. ### String Fields In the **expert search**, string fields support queries with **multiple values** and **ranges**. You can search for multiple values by separating them with a comma. Values must be entered **without spaces** between the comma and the next value. Example: `value1,value2,value3` This returns all records where the field matches **any of the specified values**. You can also define a range using the following syntax: `from - to`. This returns all values that fall **between the defined start and end values**. When working with ranges in string fields, it is important to understand that the comparison is based on **alphabetical order**, not numerical order. For example, if the data contains: `A 1`, `A 3`, `A 5` A search for: `A1 - A10` will only return: `A 1`, because strings are sorted alphabetically and `"A10"` is considered smaller than `"A2"`. This behavior is a characteristic of the underlying search engine. To work correctly with alphanumeric ranges, numbers should be **zero-padded**. Example: `A 01`, `A 03`, `A 05` A range like: `A01 - A10` will then return the expected results. ### File Fields For **file upload fields**, several **file-specific attributes** are automatically indexed and available for searching. These attributes allow you to search not only for the presence of a file, but also for technical details, metadata, and content-related properties of the uploaded file. This makes it possible to precisely locate records based on file characteristics.

FIELD	DESCRIPTION
Class	The general category of the file (for example image, video, audio, or document). Depending on the class, different fields will be shown.
Type	The specific file type (for example JPEG, PNG, PDF, MP4). Only shows file types that have been uploaded.
Unit	The measurement unit used for technical properties, such as pixels or file sizes.
Size	The file size. This field is searchable as a range, allowing you to find files within a specific size span (for example from 1 MB to 10 MB). Leaving one boundary empty performs an open-ended range search.
Width	The width of the file. This field is searchable as a range, allowing you to find files within specific width boundaries. Leaving one boundary empty performs an open-ended range search.
Height	The height of the file. This field is searchable as a range, allowing you to find files within specific height boundaries. Leaving one boundary empty performs an open-ended range search.
Format	The orientation of the file. Possible values are Landscape, Portrait, and Square.
Status	The processing or availability status of the file.
Filename	The original name of the uploaded file.
Date	The file-related date, choose between Upload Date or Creation Date. This field is searchable as a date range. Entering only one boundary performs an open-ended range search.
Asset ID	The unique identifier assigned to the file by the system.
Search in File	Enables full-text search within the file content for supported file types.
