Improve AF Search PI AF SDK with ORed option
PI AF SDK - Search Query Syntax - Filters
Allow results to be ORed. Currently Results can only be ANDed.
This is planned for the 2018 R2 release for AF based searches. Note that while the user interface in PSE will allow OR clauses to be typed in, there will not yet be a user interface in 2018 R2 to help you build OR clauses.
