Subject [jira] [Commented] (SOLR-1926) add hl.q parameter
Date Mon, 07 Nov 2011 05:59:51 GMT


Koji Sekiguchi commented on SOLR-1926:

I misunderstood Hoss's suggestion as I read it too fast. hl.text should be multiValued and
its value should be analyzed.

would it make more sense to imagine a multivalued "hl.text" param, such that each value is
passed to the analyzer for each "hl.fl" field, and the resulting terms are all highlighted
(in their respective fields) ... thus bypassing the complications of extracting temrs from

would that be more useful or less useful?

I like the idea! But as doHighlighting() method takes Query, it is not easy. I'd like to open
a separate ticket for it.

> 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.
