Erik Hatcher commented on SOLR-1954:
------------------------------------
No, we're not talking about the same thing. Here's what I'm suggesting:
{code}
{
'responseHeader'=>{
'status'=>0,
'QTime'=>15},
'response'=>{'numFound'=>3,'start'=>0,'maxScore'=>0.10558263,'docs'=>[
{
'id'=>'IW-02',
'name'=>'iPod & iPod Mini USB 2.0 Cable',
'manu'=>'Belkin',
'weight'=>2.0,
'price'=>11.5,
'popularity'=>1,
'inStock'=>false,
'store_0_d'=>37.7752,
'store_1_d'=>-122.4232,
'store'=>'37.7752,-122.4232',
'manufacturedate_dt'=>'2006-02-14T23:55:59Z',
'cat'=>[
'electronics',
'connector'],
'features'=>[
'car power adapter for iPod, white'],
'score'=>0.10558263}]
},
'facet_counts'=>{
'facet_queries'=>{},
'facet_fields'=>{
'cat'=>[
'electronics',3,
'connector',2,
'music',1],
'manu_exact'=>[
'Belkin',2,
'Apple Computer Inc.',1]},
'facet_dates'=>{}},
'highlighting'=>{
'IW-02'=>{
'features'=>['car power adapter for <em>iPod</em>, white'],
'name'=>['<em>iPod</em> & <em>iPod</em> Mini USB 2.0 Cable']}},
'highlighting-extended-info'=>{
'IW-02'=>{
'text_startPos'=>[5]
},
'spellcheck'=>{
'suggestions'=>[]}}
{code}
That way the highlighting section remains untouched, with extra stuff in a
'highlighting-extended-info' (let's use a shorter name though) section as a
direct child of the root response, just like 'highlighting' is.
> Highlighter component should expose snippet character offsets and the score.

> Key: SOLR-1954
> URL: https://issues.apache.org/jira/browse/SOLR-1954
> Project: Solr
> Issue Type: New Feature
> Components: highlighter
> Reporter: David Smiley
> Priority: Minor
> Attachments: SOLR-1954_start_and_end_offsets.patch
>
>
> The Highlighter Component does not currently expose the snippet character
> offsets nor the score. There is a TODO in DefaultSolrHighlighter indicating
> the intention to add this eventually. This information is needed when doing
> highlighting on external content. The data is there so its pretty easy to
> output it in some way. The challenge is deciding on the output and its
> ramifications on backwards compatibility. The current highlighter component
> response structure doesn't lend itself to adding any new data, unfortunately.
> I wish the original implementer had some foresight. Unfortunately all the
> highlighting tests assume this structure. Here is a snippet of the current
> response structure in Solr's sample data searching for "sdram" for reference:
> {code:xml}
> <lst name="highlighting">
> <lst name="VS1GB400C3">
> <arr name="text">
> <str>CORSAIR ValueSelect 1GB 184-Pin DDR <em>SDRAM</em>
> Unbuffered DDR 400 (PC 3200) System Memory - Retail</str>
> </arr>
> </lst>
> </lst>
> {code}
> Perhaps as a little hack, we introduce a pseudo field called
> text_startCharOffset which is the concatenation of the matching field and
> "_startCharOffset". This would be an array of ints. Likewise, there would
> be another array for endCharOffset and score.
> Thoughts?
