Search not working after Fall 2018 update

I noticed that one of my searches was not working after my KB was updated on the weekend. I’ve figured out that it was the " is fully contained in" operator that was no longer functioning. I read that any searches with that operator were supposed to be automatically converted to the new “overlaps with items in”, however this one obviously wasn’t.

Is there an easy way that I can search all my Searches to see if the old operator still remains in any of them?

Hi Paul, please can you submit this as a bug. Support will be able to work with you to locate any broken searches.

Not all instances of ‘Fully Contained In’ should have been converted into the new operator, only ones used on multivalue linked fields.

Done … thanks Jack.
