Question 1)
I also have a question about position. I added a doc 5 and 6
{{monospaced}}
DocData docsContent[] = { new DocData("john smith", "1"),
new DocData("johathon smith", "2"),
new DocData("john percival smith goes on a b c vacation", "3"),
new DocData("jackson waits tom", "4"),
new DocData("johathon smith john", "5"),
new DocData("johathon mary gomes smith", "6"),
};
{{monospaced}}
for test
checkMatches("\"(jo* -john) smyth\"", "2"); // boolean logic with
would document 5 be returned or just doc 2 should be returned,
I'm assuming position is always important and doc 5 is supposed to be returned,
correct?
Question 2)
Should these 2 queries behave the same when we fix the problem
// checkMatches("\"john -percival\"", "1"); // not logic doesn't work
// checkMatches("\"john (-percival)\"", "1"); // not logic doesn't work
Question 3)
checkMatches("\"jo* smith\"~2", "1,2,3,5"); // position logic works.
doc 6 is also returned, so this feature does not seem to be working.
Question 4)
The usage of AND and AND_NEXT_TO is confusing to me
the query
checkMatches("\"(jo* AND mary) smith\"", "1,2,5"); // boolean logic with
returns 1,2,5 and not 6, but I was only expecting 6 to be returned,
Can you describe what is the behavior here.
Looks like the and is converted into a OR.
What is the behavior you want to implement?

Look like the and is convert into a OR, that the case.

> Key: LUCENE-1486
> URL: https://issues.apache.org/jira/browse/LUCENE-1486
> Project: Lucene - Java
> Issue Type: Improvement
> Components: QueryParser
> Affects Versions: 2.4
> Reporter: Mark Harwood
> Assignee: Mark Harwood
> Priority: Minor
> Fix For: 2.9
>
> Attachments: ComplexPhraseQueryParser.java,
> junit_complex_phrase_qp_07_21_2009.patch,
> junit_complex_phrase_qp_07_22_2009.patch, LUCENE-1486.patch,
> LUCENE-1486.patch, LUCENE-1486.patch, LUCENE-1486.patch,
> TestComplexPhraseQuery.java
>
>
> An extension to the default QueryParser that overrides the parsing of
> PhraseQueries to allow more complex syntax e.g. wildcards in phrase queries.
> The implementation feels a little hacky - this is arguably better handled in
> QueryParser itself. This works as a proof of concept for much of the query
> parser syntax. Examples from the Junit test include:
> checkMatches("\"j* smyth~\"", "1,2"); //wildcards and fuzzies
> are OK in phrases
> checkMatches("\"(jo* -john) smith\"", "2"); // boolean logic
> works
> checkMatches("\"jo* smith\"~2", "1,2,3"); // position logic
> works.
>
> checkBadQuery("\"jo* id:1 smith\""); //mixing fields in a
> phrase is bad
> checkBadQuery("\"jo* \"smith\" \""); //phrases inside phrases
> is bad
> checkBadQuery("\"jo* [sma TO smZ]\" \""); //range queries
> inside phrases not supported
> Code plus Junit test to follow...
