Hi folks, have any of you successfully implemented LSH (MinHash) in
Solr? If so, could you share some details of how you went about it?
I know LSH is available in Mahout, but was hoping if someone has a
solr or Lucene implementation.
Thanks

Look up multicore solr. Another choice could be ElasticSearch - which
is more straightforward in managing multiple indexes IMO.

We have used both Solr and graph databases for our XML file indexing. Both
are equivalent in terms of performance, but a graph db (such as Neo4j)
offers a lot more flexibility in joining across the nodes and traversing.
If your data is strictly hierarchical Solr might do it, alternately suggest
is not a static one. It must update
on the fly. As I know, Lucene index is not suitable to be updated too
frequently. If so, how to deal with that?

Lucene has a mechanism to boost up/down documents using your custom
