Dear Lucene Users,
Is there a way or has someone been able to implement an ordered
proximity search. Lucene currently uses the "word1 word2"~5 query
to find tokens that are within 5 words of each other in any order.
What I've been asked to do is find only the results that are for
instance within 5 words of each other in the order the query was
written.
Yup... SpanNearQuery supports ordered and unordered proximity.
PhraseQuery does not, though. QueryParser will only create a
PhraseQuery though, so you'll need to subclass QueryParser to add
this functionality. There is an example of this in the free code of
Lucene in Action - http://www.lucenebook.com

For a scenario like
text:"blah blah blah. Section 1 of Primary Act 1976, s1. Dogs Act
1999, s3 blah blah blah"
Say I wanted to find the Dogs Act Section 1 using text:"dogs act
s1"~5 query would give the above record when it wasn't in context.
This is the reason for wanting results in order to stop these
incorrect results.
Any help would be greatly appreciated.
