“Search” section#

The “Search” section is designed to search by photo, event (event ID), and face (face ID: “External ID”, “Face ID”). This section displays all detection face and body recognition events that match the search conditions. General view of the “Search” section is shown below (Figure 16).

If departments are created, and users and event sources are attached to these departments, the user can search only for those events that were recorded by the event sources of his department.

The “Search” section contains the following blocks:

Search options:
“Photo” — search by uploaded photo image:
- field for uploading a photo image;
“Event” — search by registered event in the system:
- “Event ID” — identifier of the event of detection and attribute extraction;
“Face” — search by registered face in the system:
- “External ID” — external face identifier;
- “Face ID” — face identifier that is created in the LUNA PLATFORM 5 system as a result of a detection event and attribute extraction;
Searching results:
“Events”:
- “Display search image” checkbox — disable if you need to hide the column with the original photo;
- “Search result”;
- “Search image”;
- “Details”;
“Faces”:
- “Display search image” checkbox — disable if you need to hide the column with the original photo;
- “Search result”;
- “Search image”;
- “Details”;
“Filters”.

A short description of the elements and parameters of the filter block in the "Search" section is presented in the table (Table 6).
