Fine, then write the query that way: +foo +bar baz
But it still doesn't sound as if any of this relates to prospective
search/percolate.

"can match a user's query against all the terms in the index" - that's
exactly what Lucene and Solr have done since Day One, for all queries.
Percolate actually does the opposite - matches an input document against a
registered set of queries - and doesn't match against indexed documents.
Solr does support Lucene's "min should match" feature so that you can
specify, say, four query terms and return if at least two match. This is
the "mm" parameter.
I don't think you understand me.
Say I only have one document indexed and it's contents are "Foo Bar". I want
this documented returned if and only if the query has the words "Foo" and
"Bar" in it. If I use a mm of 100% for "Foo Bar Bazz" this document will not
be returned because the full user query didn't match. I i use a 0% mm and
search "Foo Baz" the documented will be returned even though it shouldn't.

You seem to be mixing a couple of different concepts here. "Prospective

matter, but how to match terms is completely different.
Solr does not have the exact "percolate" feature of ES, but your examples
don't indicate a need for what percolate actually does.

See:

Try to clarify your requirements... or maybe min-should-match was all you
needed?

Subject: Percolate feature?
We have a set number of known terms we want to match against.
In Index:
"term one"
"term two"
"term three"
I know how to match all terms of a user query against the index but we
would like to know how/if we can match a user's query against all the
terms in the index?
Search Queries:
"my search term" => 0 matches
"my term search one" => 1 match ("term one")
"some prefix term two" => 1 match ("term two")
"one two three" => 0 matches
I can only explain this is almost a reverse search???
I came across the following from ElasticSearch
(http://www.elasticsearch.org/guide/reference/api/percolate/) and it
sounds like this may accomplish the above but haven't tested. I was
wondering if Solr had something similar or an alternative way of
accomplishing this?
Thanks
