Subject [jira] Created: (SOLR-1926) add hl.q parameter
Date Tue, 25 May 2010 16:14:25 GMT
add hl.q parameter
------------------

                 Key: SOLR-1926
                 URL: https://issues.apache.org/jira/browse/SOLR-1926
             Project: Solr
          Issue Type: Improvement
          Components: highlighter
    Affects Versions: 1.4
            Reporter: Koji Sekiguchi
            Priority: Trivial


If hl.q parameter is set, HighlightComponent uses it rather than q.

Use case:

You search "PC" with highlight and facet capability:

{code}
q=PC
&facet=on&facet.field=maker&facet.field=something
&hl=on&hl.fl=desc
{code}

You get a lot of results with snippets (term "PC" highlighted in desc field). Then you click
a link "maker:DELL(50)" to narrow the result:

{code}
q=PC
&facet=on&facet.field=something
&fq=maker:DELL
&hl=on&hl.fl=desc
{code}

You'll get narrowed result with term "PC" highlighted snippets. But, sometimes I'd like to
see "DELL" to be highlighted as well, because I clicked "DELL". In this case, hl.q can be
used:

{code}
q=PC
&facet=on&facet.field=something
&fq=maker:DELL
&hl=on&hl.fl=desc&*hl.q=PC+maker:DELL*
{code}

Note that hl.requireFieldMatch should be false (false is default) in this scenario.
