Michael Henson updated SOLR-1005:
---------------------------------
Attachment: solr-1005.zip
Patch to skip 0-length tokens in the DoubleMetaphoneFilter.
> DoubleMetaphone Filter Produces NullpointerException on zero-length token
> -------------------------------------------------------------------------
>
> Key: SOLR-1005
> URL: https://issues.apache.org/jira/browse/SOLR-1005
> Project: Solr
> Issue Type: Bug
> Components: Analysis
> Affects Versions: 1.4
> Environment: jdk 1.6.10, tomcat 6.x
> Reporter: Michael Henson
> Attachments: solr-1005.zip
>
>
> If any token given to the DoubleMetaphoneFilter is empty (Token exists, 0
> length), then the encoder will return null instead of a metaphone encoded
> string. The current code assumes that there will always be a valid object
> returned.
> Proposed solution: Make sure 0-length tokens are skipped at the top branch
> where the code checks whether or not we have a Token object at all.
