See ComplexPhraseQueryParser? Like the standard QueryParser it uses quotes to define a phrase but also interprets any special characters between the quotes e.g. ( ) * ~ The syntax and its interpretation is outlined here: http://goo.gl/6gni1 (I saw someone else was asking for this recently) ----- Original Message ----- From: Dave Seltzer <dselt...@tveyes.com> To: java-user@lucene.apache.org Cc: Sent: Wednesday, 22 August 2012, 1:37 Subject: Re: Creating Span Queries from Boolean Queries Well I was hoping that someone knew of a recursive solution to rewriting Boolean queries of arbitrary depth. I suppose If I can rewrite "london olympics" AND (football OR soccer) NOT nfl into "London Olympics" within_5_words_of (football or soccer) not_within_5_words_of nfl Then I should be able to use the same logic to operate on a BooleanQuery occurring within a BooleanClause. -D On Tue, Aug 21, 2012 at 7:26 PM, Jack Krupansky <j...@basetechnology.com>wrote: > Give us an example of what you are really trying to match. > > SpanNearQuery takes a list of clauses, which can be SpanTermQuery to match > a single term or SpanNearQuery to match a nested span.
