Bill Au commented on SOLR-24:
-----------------------------
The TokenStream looks OK. It contains "i", "pod", and "ipod".
I also tried using different query terms.
q=pod produces the same output as q=ipod.
q=iPod produces output with the extra "i" highlighted as well, ie
<lst name="highlighting">
<lst name="id=IW-02">
<arr name="name">
<str><em>i</em><em>iPod</em> &
<em>i</em><em>iPod</em> Mini USB 22.0 Cable</str>
</arr>
</lst>
<lst name="id=F8V7067-APL-KIT">
<arr name="name">
<str>Belkin Mobile Power Cord for <em>i</em><em>iPod</em>
w/ Dock</str>
</arr>
</lst>
</lst>
> Add Highlighting to standard request handler
> --------------------------------------------
>
> Key: SOLR-24
> URL: http://issues.apache.org/jira/browse/SOLR-24
> Project: Solr
> Type: New Feature
> Components: search
> Reporter: Mike Klaas
> Attachments: highlight_patch_v1.diff
>
> This patch adds highlighting functionality to solr request handlers it also
> refactors StandardRequestHandler to use the common functionality provided in
> SolrPluginUtils. I'd have preferred to do two separate patches, but creating
> two mutually-dependent patches on a repo without being able to commit a
> revision was daunting.
> -----------------------------------
> Refactoring StandardRequestHandler:
> 1. Moved solr.util.CommonParams to its own class. Removed DisMax-specific
> parameters, and placed in a subclass.
> 2. StandardRequestHandler uses CommonParams to store config-time parameter
> values (new feature)
> 3. StandardRequestHandler uses SolrPluginUtils methods for duplicate
> functionality
> 4. Some of said SPU methods have grown a "params" parameter to enable them to
> use default values. (Note: instead of passing this around, something like a
> RequestHelper class which carries the SolrRequest and Param values would be
> useful. This class could house the utility methods that require Request
> parameters).
> 5. SolrPluginUtils.getParam() only uses the default parameter if it is null,
> not blank.
> --------------------------------------
> Highlighting:
> 1. Highlighting is controlled by three request parameters:
> highlight: list of fields to highlight, or highlight the default field if
> at all present
> maxSnippets: maximum number of snippets to return for each field
> highlightFormatterClass: 'solr.<classname>' or full package path of
> highlight.Formatter subclass to use in highlighting.
> 2. Default formatter is to use <em> tags. There are issues with this
> approach, but are mitigated with the ability to specify a custom Formatter.
> Definately should consider alternatives (a custom xml approach to denote
> highlit regions will require some Highlighter package hackery).
> 3. Document summaries are returned as a separate element under <response>
> format is still up for discussion.
