Subject [jira] [Commented] (SOLR-3897) Preserve multi-value fields during hit highlighting
Date Wed, 03 Oct 2012 20:38:07 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3897?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13468808#comment-13468808

Joel Bernstein commented on SOLR-3897:
--------------------------------------

I was incorrect, fragsize works with the default highlighter. I still vote for leaving the
original patch as it is and documenting the use of snippets and fragsize with it. This will
provide flexibility to work with different use cases.

Another test case can be added to test field values with the fragsize param.

> The behavior of the default Solr hit highlighter on multi-value fields is to only return
the values that have a hit and sort them by score.
> This ticket supplies a patch that adds a new highlight parameter called "preserveMulti"
which can be used on a feild by field basis to return all of the values in their original
order. If this parameter is used, the values that have a hit are highlighted and the ones
that do not contain a hit are returned un-highlighted.
> The "preserveMulti" parameter works with the default standard highlighter and follows
the standard highlighting conventions.
> Sample usage for a field called "cat":
> f.cat.hl.preserveMulti=true
