We have one of our applications running in Pega cloud shared instance where several other applications are also running.

We want to enable the checkbox "For Specified properties" (which points to DSS - indexing/distributed/enable_onlyselectedfieldsinfulltextsearch) in Configure->System->Settings->Search (see screenshot below), so that the searching via the OOTB search gadget will only be possible for the properties mentioned in the "Custom Search properties" application specific class instance.

Issue: If we enable the "For specific properties" checkbox, the existing search behaviour of all other applications will get impacted e.g. if there are no specific properties mentioned in other application class instances (which is the case for most applications), the search gadget will stop working for those applications e.g. search with pyID etc.

Requirement: We need a solution by which this pega OOTB search behaviour can be enabled for specific properties for a specific application without impacting other application on the same instance.
