[jira] [Commented] (SOLR-3955) Return only matched multiValued field

["Jacob Xu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-3955?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14169192#comment-14169192 ] 

Jacob Xu commented on SOLR-3955:
--------------------------------

This is a urgent issue that should be concerned. Specially, when the multiValued filed has large number of values (>1K), it will cost high memory and I/O to return all values.

> Assuming a multivalued, stored and indexed field named "comment". When performing a search, it would be very helpful if there were a way to return only the values of "comment" which contain the match. For example:
> When searching for "gold" instead of getting this result:
> <doc>
>     <arr name="comment">
>         <str>Theres a lady whos sure</str>
>         <str>all that glitters is gold</str>
>         <str>and shes buying a stairway to heaven</str>
>     </arr>
> </doc>
> I would prefer to get this result:
> <doc>
>     <arr name="comment">
>         <str>all that glitters is gold</str>
>     </arr>
> </doc>
> (psuedo-XML from memory, may not be accurate but illustrates the point)
> Thanks.
