You've not really provided enough detail, but I'm going to guess
that your OS update included a change in collation definitions
that left any indexes on text columns essentially corrupt.
The LIKE queries probably weren't affected because they didn't
rely on indexes.
Reindexing the indexes should have been enough to fix it.
