Change valid to date to see 30 days past

[breana2014]

I want to be able to see knowledge articles in the employee center and the global search ,in a specific knowledge base, 30 days past their valid to date. I tried to update the AI search sources by adding valid to at or after last 30 day. I also added that condition to the text search table with valid to relative after 30 days ago. I made sure for both configurations that I specified the specific knowledge bases, For some reason this is messing with the OOB functionality for all other articles and now I am seeing them 30 days past as well even though I made sure to only add the specific knowledge bases I needed to the conditions. Any thoughts?

Regarding AI Search: You may want to double check the condition builder for Search Sources. The only thing I can think of is that the OR condition is on there at the parent level instead of an AND. 

Is this for analysis purposes or for everyone? If it's purely for analytical purposes, I would recommend creating a new search source and search profile so that it doesn't affect the portal as a whole.
