Example: a search in virtual agent on "issue" did not result in the raise an issue record producer being returned, even though this was defined as a search word in the topic
Searching the 'issue' keyword will not bring any result in this instance because 'issue' has been set as a 'Stop Word'
VA uses global search functionality to return any matching topic and it doesn't return any result for 'issue'. You can quickly test this behavior from the sys_cs_topic table as well.
*'issue' is set as 'Not a stop word' for sys_metadata text index. Therefore, you can only see results from sys_metadata-extended tables (i.e. sc_cat_item).
Please either keep the current configuration in place and remember that 'issue' keyword will not bring any results or mark 'issue' as 'Not a stop word' for sys_cs_topic text index.
