Segments allow you to use applied set of filters in future or create a sub-collection from it. The only information needs to create a segment for collection is a name and filters.
There are two ways to create Segment – on Collection List or Collection Settings page.
To create a new Segment:
Add filters on Collection List page (as described on Filtering)
Click on plus button next to the filters list (New segment from filters tip will appear) as on screenshot below.
Add Segment popup will appear. Enter Segment Name and click Add Segment button.
Open Collection Settings page one of the following ways:
Collection List/Edit page → Customize Interface → System Settings
Project Settings → Collections → Choose Collection
Go to Segments tab (1)
Click Add Segment button (2)
Fill segment information:
Segment Name (3)
Segment Filters (4) - adding filters is just the same as on Collection List page. Click Add button, choose parameters in appeared popup: Filtering Field, Type of Filter and Filter Value.
Click Create button
For some complicated cases when general filtering is not enough you can create Segment from SQL query. Create segment just like in case of Create Segment on Collection Settings Page, but instead of adding filters choose SQL type for segment and enter SQL query that will return records ID in the first column of query result.
