How to achieve dynamic field value filtering after main search?

[amerineni]

Hello,  I'm trying to filter my events/results after evalulating the field name and value dynamically using eval. 

index=XXXX  YYYYYYY  | eval field_name=PPPP | eval field_value=KKKK | search field_name=field_value

I tried  below options, but none worked.

index=XXXX   [|gentimes start=-1 | eval space="Test"| table space]

index=XXXX   [|gentimes start=-1 | eval space="Test"| fields space]

I am not entirely clear what it is you are trying to do - does this help?

index=XXXX  YYYYYYY  | where PPPP="KKKK"

I need to evalute some search criteria based on the inputs selected and peform the search.
