Subject [jira] Commented: (SOLR-1926) add hl.q parameter
Date Tue, 25 May 2010 16:32:24 GMT


Hoss Man commented on SOLR-1926:

Koji: highlighting isn't something i think about much, but i have to wonder if an alternate
"highlight _query_" is really the best concept here (specificly the part where it's parsed
by a QParser into a Query and then the terms are extracted)

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?

(although: i suppose hl.requireFieldMatch wouldn't really make any sense in a situation like
this ... and there'd be no way to say "highlight DELL only in the maker field")

Hmmm... anyway, just something i wanted to toss out there in case it inspired you.

>             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.
