I keep asking people this eternal question: What training or doc are you
reading that is using this term "exact match"? Clearly the term is being
used by a lot of people in a lot of ambiguous ways, when "exact" should
be... "exact".
I think we need to start using the term "exact match" ONLY for string field
queries, and that don't use wildcard, fuzzy, or range queries. And maybe
also keyword tokenizer text fields that don't have any filters, which might
as well be string fields.

Subject: Re: Solr: Tricky exact match, unwanted search results
*Erick*, thank you for help!
For exact match I still want:
to use stemming (e.g. for "sleep" I want the word forms "slept", "sleeping",
"sleeps" also to be used in searching)
to disregard case sensitivity
to disregard prepositions, conjunctions and other function words
to match only docs having all of the query words and in the given order
(except function words)
to match only docs if there are no other words in the doc field besides the
words in the query
to use synonyms (e.g. "GB" == "gigabyte", "Television" == "TV")

The easiest way to make your examples work wouldbe to use a copyField to
an "exact match" field thatuses the KeywordTokenizer
The KeywordTokenizer treats the entire field as a single token, regardless
of its content. So this does not fit to my requirements.

You'll have to be a little careful to escape spaces for muti-term bits,
like exact_field:pussy\ cat.
Hmm... I don't care about quoting right now at all. But should I?

As far as your question about "if" and "in", what you're probably getting
here is stopword removal, but that's a guess.
I have the following document:After I disabled solr.StopFilterFactory for
analyzer type="query" Solr stopped returning this document for the query:
http://localhost:8983/solr/lexikos/select?q=phraseExact%3A%22on+a+case-by-case%22.Can
I somehow implement the desired "exact match" behavior?
