    Attachment: WordDelimiterFilter.patch

> Add the ability to preserve the original term when using WordDelimiterFilter
> ----------------------------------------------------------------------------
>
>          Key: SOLR-14
>          URL: http://issues.apache.org/jira/browse/SOLR-14
>      Project: Solr
>         Type: Improvement

>   Components: search
>     Reporter: Richard "Trey" Hyde
>  Attachments: WordDelimiterFilter.patch
>
> When doing prefix searching, you need to hang on to the original term othewise you'll miss many matches you should be making.
> Data: ABC-12345
> WordDelimiterFitler may change this into
> ABC 12345 ABC12345
> A user may enter a search such as 
>  ABC\-123*
> Which will fail to find a match given the above scenario.
> The attached patch will allow the use of the "preserveOriginal" option to WordDelimiterFilter and will analyse as
> ABC 12345 ABC12345  ABC-12345 
> in which case we will get a postive match.
