Subject [jira] [Commented] (SOLR-1715) Externally Generated Filters
Date Thu, 26 May 2011 17:44:48 GMT


roman commented on SOLR-1715:

I noticed this question at the Lucene conference, and it seems suspiciously similar to what
we solved as well while developing the intgration between our system and Solr - if you are
still at LR, you can come to see my talk about embedding Python in Solr --
 at 15:45

I know, this will not be considered a 'kosher' solution ;-), but it could help -- in fact,
we can embed not only Python, but also (almost any) C/C++ app inside 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.
