Nikhil Chhaochharia commented on LUCENE-1486: --------------------------------------------- LUCENE-5205 is very interesting, thanks for pointing me to it. However, we should still try to get LUCENE-1486 closed - most of the work has already been done and it may be useful in certain cases where the full power of LUCENE-5205 is not required. > Wildcards, ORs etc inside Phrase queries > ---------------------------------------- > > Key: LUCENE-1486 > URL: https://issues.apache.org/jira/browse/LUCENE-1486 > Project: Lucene - Core > Issue Type: Improvement > Components: core/queryparser > Affects Versions: 2.4 > Reporter: Mark Harwood > Priority: Minor > Fix For: 4.7 > > Attachments: ComplexPhraseQueryParser.java, LUCENE-1486.patch, > LUCENE-1486.patch, LUCENE-1486.patch, LUCENE-1486.patch, LUCENE-1486.patch, > LUCENE-1486.patch, LUCENE-1486.patch, Lucene-1486 non default field.patch, > TestComplexPhraseQuery.java, junit_complex_phrase_qp_07_21_2009.patch, > junit_complex_phrase_qp_07_22_2009.patch > > > 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... -- This message was sent by Atlassian JIRA (v6.1.5#6160) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
