Pega Knowledge tag search performance degrades



Pega Knowledge tag search performance degrades.

Error Messages

PEGA0005 alerts on query: SELECT "PXLINKEDREFFROM" AS "pxLinkedRefFrom" ,   "PXLINKEDREFTO" AS "pxLinkedRefTo" ,   "PZINSKEY" AS "pzInsKey" from CPE_BPRMS.pr_link_work_tag  WHERE ( "PXLINKEDREFFROM" = ? ) AND (  "PXOBJCLASS" = ?  ) *

Steps to Reproduce

Utilize Pega Knowledge tag search.

Root Cause

Logic in Knowledge Management executed the query to filter tags even when a result set was already filtered. This created additional extraneous tag search queries.


Apply HFix-59683.
