Unable to search for the SQL keyword BETWEEN
I've found a bug in the search engine. It is very reproducible.
Go to EL&U SE
Search for that that. The search engine says that there are no matches. I don't know why it returns no results, but the engine works with other phrases such as wind wind. The Google Search for that that, however, finds many results on the site.
So for some reason, the search engine is not returning any matches for this search, but works perfectly fine with other searches.
