The easiest way to make your examples work would
be to use a copyField to an "exact match" field that
uses the KeywordTokenizer (and perhaps a lowercase filter).
Then your exact match would be satisfied by a simple
wildcard search for cat*.
You'll have to be a little careful to escape spaces for
muti-term bits, like
exact_field:pussy\ cat.
Quoting these is sometimes tricky.
Anyway, as the thread you linked to says, details matter
a lot in this case. The keyword tokenizer won't let you find
"dog has" in a field populated with "my dog has fleas" for
instance with this techinque.
As far as your question about "if" and "in", what you're probably
getting here is stopword removal, but that's a guess. Try it
again without including a stopword filter factory to test that
out.
Best,
Erick
