When searching, how whitespace should be handled.  Options are: "skip"
(default in 2.3 and earlier series) - where a search for "equi" would match
"the quick brown fox".  "merge" - the default, where "he  qu" would match
"the quick   brownfox", and "keep", where whitespace must match exactly.
The default of "merge" is recommended for most cases - it's a good
compromise which keeps words separate.
