Subject [jira] Commented: (SOLR-1715) Externally Generated Filters
Date Wed, 13 Oct 2010 22:24:33 GMT


Tom Burton-West commented on SOLR-1715:

+1 for work on this feature.

Other use cases include :
  1) creating custom sub-collections of documents (Example that won't scale without this issue
being addressed :
2) tagging documents 
3) anything that might need querying a relational database (i.e. complex joins) 
4) sort of an alternative to implementation of incremental field update in lucene/solr (i.e.
updated fields stored outside of lucene/solr)

 For instance, I may have run a clustering task over my corpus and the results may be stored
in HDFS (Hadoop).  A given cluster will have a centroid and a bunch of points that are in
the cluster.  The points are labeled by doc id (the Solr doc id) from the index.  
> Another example is I may have an external security system that can provide info on which
documents are available to a user.
