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 10).

Add filter by meta***

Allows you to fill in a set of blocks to create a filter by the "meta" field. The number of meta filters is unlimited. The following blocks are required to be filled in when creating a filter by meta:

  • Key—the full path to the required meta field connected with events.

  • Value—any valid value for the meta field.

  • Type—selection of the data type stored in this meta field. The data type displays available operators and converts values into the desired data type when sent to the API.

  • Operator—select operators for a given data type from the list. Operator type depends on the selected data type (for more details see LUNA PLATFORM 5 API, "get events" section)

***For advanced users

To search by face or body image, select the "Photo" section, click on the field to upload an image from your computer, or drag and drop a photo into this field.

To find similar faces or events with the face or body, select one face or body by clicking on it on the uploaded photo image. Then, in the filter block, select the necessary search options and click "Filter". To reset the parameter values, click the "Reset" button. The search results will be displayed at the bottom of the page (Figure 12).
