Duh, didn't realize you could set inOrder in Solr. Y, that's the better
solution.

The other thing to check is the ComplexPhraseQueryParser, see:
https://cwiki.apache.org/confluence/display/solr/Other+Parsers#OtherParsers-ComplexPhraseQueryParser
It uses the Span queries to build up the query...

Hi Johannes,
I suspect that Scott's answer would be more efficient than the following,
and I may be misunderstanding the problem!
This type of search is supported at the Lucene level by a SpanNearQuery with
inOrder set to false.
So, how do you get a SpanQuery in Solr? You might want to look at the
SurroundQueryParser, and I have an alternate (LUCENE-5205/SOLR-5410) here:
https://github.com/tballison/lucene-addons.
If you do find an appropriate parser, make sure that your position increment gap
is > 0 on your text field definition, and then you'd never incorrectly get a
hit across field entries of:
[0] A B
[1] C

Tim

Hello all,
we are facing the following problem: we use a multivalued string
field that contains entries of the kind A/B/C/, where A,B,C are terms.
We are now looking for a simple way to also find all permutations of
A/B/C, so e.g. B/A/C. As a workaround we added a new field that
contains all entries alphabetically sorted and guarantee sorting on the user
side.
However - since this is limited in some ways - is there a simple way
to either index in a way such that solely A/B/C and all permutations
are found (using e.g. type=text is not an option since a term could
occur in a different entry of the multivalued field) or trigger an
alphabetical sorting of incoming queries.
Thanks a lot for your feedback, best regards
Johannes
