Apologies for the self-promotion...LUCENE-5205 and its Solr cousin (SOLR-5410)
might help. I'm hoping to post updates to both by the end of next week. Then,
if a committer would be willing to review and add these to Lucene/Solr, you
should be good to go.
Take a look at the description for LUCENE-5205and see if that capability will
meet your needs. Thank you.
Best,
Tim

Subject: Fwd: Span Not Queries
Please help me out with earlier query.
In short:
1. Can we change the QueryParser.jj file to identify the SpanNot query as a
boolean clause?
2. Can we use ComplexPhraseQuery Parser to support SpanOR and SpanNOT queries
also?
For further explanation, following are the examples.

A Boolean inside a ordered query or ordered query inside a Boolean
. Currently i am thinking of changing the QuerParser.jj file to identify
the SpanNot query and use Complex Phrase Query Parser of Lucene for parsing
complex queries . Can you suggest better way of achieving this.*
*Following are the list of additions that i need to do in SOLR.*
*1. Span NOT Operator* .
2.Adding Recursive and Range Proximity
*Recursive Proximity *is a proximity query within a proximity query
Ex: " "income tax"~5 statement" ~4 The recursion can be up to any
level.
* Range Proximity*: Currently we can only define number as a range we
want interval as a range .
Ex: "profit income"~3,5 , "United America"~-5,4
3. Complex Queries
A complex query is a query formed with a combination of Boolean operators
or proximity queries or range queries or any possible combination of these.
Ex: "(income AND tax) statement"~4
" "income tax"~4 (statement OR period) "~3
(" income" SPAN NOT "income tax" ) source ~3,5
Can anyone suggest us some way of achieving these 3 functionalities in SOLR
???
