This is fine because that's how Lucene works. However, I do not want to get a
hit if I do:
Field1:A AND Field2:D
The reason that I don't want a hit is because A is the first element in Field1
and D is the second element in Field2. I only want a hit when both values are
at the same array index. Is there a way to do this? Thank you in advance for
your help.
With a bit of fudging, you may be able to use a SpanNearQuery to do this
-- though you'll need to change your analyzer's positionIncrementGap,
and depending on how many tokens you'll have for each field (if it
varies between fields) you may need to patch Lucene to change the way
the gaps are calculated.
I've done a prototype of exactly this (SpanNearQuery and analyzer
changes) for a very similar situation here and it works BRILLIANTLY --
massively, massively faster for us than indexing a new document for each
set of 'subfields'.
I've put some patches against
https://issues.apache.org/jira/browse/LUCENE-1494 -- I think this
approach might work for you. Let me know if you need clarification.
Cheers,
Paul
