[AIS] Older catalog items and knowledge articles are not returned in the Search Results, as the Indexed Sources on these tables have a Retention Policy setIssue The AI Search application is not returning older Catalog Items or Knowledge Articles in the Search results. When checking the Search Source linked to the Indexed Source on tables [sc_cat_item] and [kb_knowledge], all the Catalog Items and Knowledge Articles are returned in the Source Preview.When checking the filters on the Search Sources and Indexed Sources, the Catalog Items and Knowledge Articles are not excludedPerforming a reindex of the Indexed Source on either the Catalog Item [sc_cat_item] or the Knowledge Article [kb_knowledge] table does not resolve the issue and the older Catalog Items or Knowledge Articles are still not returned in the Search Results.CauseA retention policy has been added to the Indexed Source on table [sc_cat_item] and/or [kb_knowledge]. As per our documentation on Indexed source retention policies, indexing large source tables, such as the Task [task] table and tables that extend it, can add significant numbers of records to the AI Search index. To limit the set of source table records indexed based on the time since they were last updated, select a retention policy for your indexed source. Out-of-box, we provide the following four Retention policies - Resolution Tables Catalog Item [sc_cat_item] and Knowledge Article [kb_knowledge] are not extended from the Task [task] table, and so should not have a retention policy, otherwise it can exclude older Catalog Items or Knowledge Articles from being indexed. For these Indexed Sources on table [sc_cat_item] and/or [kb_knowledge], we recommend to use Indexed source filter conditions to exclude records from these tables from indexing.
