Faceted search?

[Minnow Noir]

Does OrientDB support faceted search like Solr (http://wiki.apache.org/solr/SolrFacetingOverview) and other products?  There's no mention of it anywhere on the web site, wiki, or Google that I can see.

In case it's not clear, I'm referring to the ability to provide counts for, and filter by, indexed field values for a given result set.  For example, on Amazon.com, if you search for a product name, you can see the number of different types of products matching the search results, and by clicking on one of the product types causes the results to be filtered down to only products that were in the original result set *AND* have product type = selected product type.

In Solr, this is done through dedicated constructs (e.g., &fq=product_type:"selected_type"). 

Thanks!

Hi,

if you model your database in a graph, you've a node for everything. Example:

Product ->* Category

So you could issue a query like.

select in().size() from Category where name = 'Book'

This is very fast and no count operation is performed.

Was interested in it more for a document database scenario.  There are great document stores with proper faceted search but none have a sql interface, which is something my customer requires. Thought I might have hit the jackpot with orientdb because it's great as a document database with sql interface.   The only other document store with faceted search and a sql interface that I know of is senseidb, but it's not active.

I would also like to know the answer to this question please. 

I think OrientDB now supports Lucene indexing and SOLR is built on Lucene. Can OrientDB be used as a search engine as a replacement to SOLR ?

I don't think it can do all of what solr can,  but adding faceted search at least  would be awesome.
