Mr. Aleem commented on LUCENE-2458: ----------------------------------- Я думаю, <a href="https://piratesfile.com/">A Place to download All PC Software</a>что лучший способ продвинуться вперед - добавить поле CJK в solr, которое по умолчанию<a href="https://piratesfile.com/hitfilm-pro-crack/">yeah this link</a>имеет противоположное<a href="https://piratesfile.com/hitfilm-pro-crack/">or you can press on link</a>поведение Ինչպես նկատել է Կոժին, կարծես թե<a href="https://piratesfile.com/hitfilm-pro-crack/">this Hit Film Software</a> will (т.е. рассматривает разделенные токены <a href="https://piratesfile.com/hitfilm-pro-crack/">как</a> полностью отдельные). > queryparser makes all CJK queries phrase queries regardless of analyzer > ----------------------------------------------------------------------- > > Key: LUCENE-2458 > URL: https://issues.apache.org/jira/browse/LUCENE-2458 > Project: Lucene - Core > Issue Type: Bug > Components: core/queryparser > Reporter: Robert Muir > Assignee: Robert Muir > Priority: Blocker > Fix For: 3.1, 4.0-ALPHA > > Attachments: LUCENE-2458.patch, LUCENE-2458.patch, LUCENE-2458.patch, > LUCENE-2458.patch > > > The queryparser automatically makes *ALL* CJK, Thai, Lao, Myanmar, Tibetan, > ... queries into phrase queries, even though you didn't ask for one, and > there isn't a way to turn this off. > This completely breaks lucene for these languages, as it treats all queries > like 'grep'. > Example: if you query for f:abcd with standardanalyzer, where a,b,c,d are > chinese characters, you get a phrasequery of "a b c d". if you use cjk > analyzer, its no better, its a phrasequery of "ab bc cd", and if you use > smartchinese analyzer, you get a phrasequery like "ab cd". But the user > didn't ask for one, and they cannot turn it off. > The reason is that the code to form phrase queries is not internationally > appropriate and assumes whitespace tokenization. If more than one token comes > out of whitespace delimited text, its automatically a phrase query no matter > what. > The proposed patch fixes the core queryparser (with all backwards compat > kept) to only form phrase queries when the double quote operator is used. > Implementing subclasses can always extend the QP and auto-generate whatever > kind of queries they want that might completely break search for languages > they don't care about, but core general-purpose QPs should be language > independent. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
