Use logical operators to group key-value pairs and backfill traits.
Use the following supported logical operators to search for key-value pairs:
|=>||Greater than/equal to|
|<=||Less than/equal to|
|Operator||Evaluates to True When|
|Contains||The value in a key-value pair contains characters specified by this operator.|
|Startswith||The value in a key-value pair starts with characters specified by this operator.|
|Endswith||The value in a key-value pair ends with the characters specified by this operator.|
You can backfill traits that include expressions containing any of the operators supported by Signal Search. In addition to these operators, trait backfilling and estimation also support the AND, OR, and AND NOT logical operators, used to combine key-value pairs within the backfilled trait expressions.
