Subject [jira] Commented: (SOLR-2087) Dismax handler not handling +/- correctly
Date Tue, 24 Aug 2010 22:38:16 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2087?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12902119#action_12902119

Hoss Man commented on SOLR-2087:
--------------------------------

It's possible some improvements could be made here, but this is functioning as originally
designed.

the pf param treats the entire q param as one big quoted phrase, without any special consideration
of other markup, in order to give a boost to things that *exactly* match the users input in
any of the pf fields. (ie: users cut/paste an exact line of text from the content they are
looking for.

in your use case, it might make sense to use an alternate tokenizer in the fields you want
to use in your "pf" (perhaps something that tokenizes away the leading "+/-" characters) 
but there are other uses cases where people have content that includes those characters, and
they want the phrase boosting part of the query to account for them.

> If I do a query like: i'm a walking contradiction it matches pf as text:"i'm_a a_walking
walking contradiction"^2.0, and it matches fine.
> If I do a query like: i'm a +walking contradiction it matches pf as text:"i'm_a a_+walking
+walking contradiction"^2.0 and doesn't match at all.
