The list search magnifying glass icon is disabled if the breadcrumb filter contains an OR statement

Adding a filter to a list of records that uses an OR statement, the list search icon in the upper left of the list becomes disabled.

 

1. Bring up a list of incidents.
2. Add a breadcrumb filter with an OR condition.
3. Note that the List Search icon (magnifying glass) becomes disabled.

 

This behaviour is by design. The search functionality currently supports queries that include AND, but does not support OR.
