: I recently modified the DefaultSolrHighlighter to support external : fields, but is there a way to do this for solr itself? I'm looking to : store a field in an external store and give Solr access to that field. : Where in Solr would I do this?
it depends on when/how you want to use that enternal info. (the performance characteristics of "use this data when highlighting N docs being returned" vs "use this data when finding N matching docs out of the entire index" are extremely differnet) If you are particularly interested in a highlighting type use case, you may want to take a look at the work Yonik & Ryan recently did adding a mechanism for a type of plugin (DocTransformer) that can modify documents that are being returned... https://issues.apache.org/jira/browse/SOLR-1566 -Hoss
