On the general topic of improving results from ?query I wanted to add an example here from a user who says that there are too many results from searches in the search UI. Their example was Berlin State Museum which returns over 3400 results, with the expected one being 3rd. Which isn't bad considering that the correct name is actually Berlin State Museums -- that search only produces 2300+ results and has the expected answer first.

@amandafrench I'm going to try fiddling around with some of the current search config, particularly AND search instead of OR, to see if we can get some better precision. Granted, search results are paginated into groups of 20, and the "correct" result often appears on the first page (if it exists).
