Darren Erik Vengroff commented on SOLR-21: ------------------------------------------ Note that this has previously been discussed elsewhere: http://wiki.apache.org/solr/FAQ#head-6b1d9dc2c14adecfe6fc5ce86448f15fc84baab9 http://www.nabble.com/Copy-Field-and-Dynamic-Fields-t1228725.html#a3252483 http://www.mail-archive.com/solr-user@lucene.apache.org/msg00019.html > Dynamic copying of fields (allow wildcard sources in copyField) > --------------------------------------------------------------- > > Key: SOLR-21 > URL: http://issues.apache.org/jira/browse/SOLR-21 > Project: Solr > Type: New Feature > Components: update > Environment: all > Reporter: Darren Erik Vengroff > Attachments: dynamicCopy.patch > > It would be really nice if it were possible to use wildcards to do things > like: > <copyField source="*_t" dest="text"/> > The above example copies all fields ending in "_t" to the "text" field. > I've put together a patch to do this. If there are mutlitple matches, all > copies are done. If there is a match in a dynamicField, then the dynamic > field is also generated, subject to the existing rules that short expressions > go first. I tried to stick to the spirit of the code as I saw it, and made > what I thought were a minimal reasonable set of changes. The patch includes > some additional tests in ConvertedLegacyTest.java to test the new > functionality. That may not be the best place for new tests, but it beats > no tests. > I'd really like to get this, or some improved variant of it into the > codebase, as it's quite important to my application. Please review and > comment/criticize as you see fit. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
