Hello Aaron,

Thanks for your reply. I will try it.

I say yes to all your questions about what you can do with Solr. 

Some background the on the technology...

Lucene is a Java library for doing full text search http://lucene.apache.org/java/docs/index.html

Solr turns lucene into a HTTP server and adds a bunch of other features such as making it easier to do faceted search (e.g. navigating a product list) and clustering http://lucene.apache.org/solr/ 

Lucandra is a set of storage plugins (or a fork, not exactly sure) for lucene so that it uses Cassandra as the storage engine rather than it's custom file format. AFAIK one of the big wins is that rather than continually build an index in the background which is periodically switched to the live index, it allows lucene to build and serve from the same index.   

Solandra is to Lucandra as Solr is to Lucene AFAIK.

Hope that helps.

Hello Aaron and Jake,

Thank you for your replay. I've worked with cassandra for 6 month but I never use Lucandra. I will try Lucandra, but I must ask (before start), Is possible reach my searching/pagination/sorting requeriments with Lucandra?

Thank you in advance,

You can also run Solr with Cassandra as the backend:

Have you considered using Solr / lucene for the search? It has a lot more search features, and it really good at faceted navigation through a product catalogue. It sounds like it would be a better fit for this task. 

You can build facets for your price ranges, do the product name thing and filter by some sort product state. Sort it any way you want and paginate it. 

Hope that helps.

I need to store "products" data (product.name, product.price, product.state and product.owner) in Cassandra 0.7 rc1.
The problem is that I need to get "products"  where product.price > XX AND product.price < XX AND product.name = XXX AND product.state = XXX. Also I need return the products with pagination sorted by one of their differents fields (product.name, product.price, product.state or product.owner). This is a for an "advance product search" functionality.
- I know that I can do the WHERE clause with secondary index of Cassandra 0.7 but I can't make the pagination because I don't know how to implement the "previuos" functionality for Row Pagination. (I can use OPP if needed)
- Also I know how to do pagination on columns but I can't do the WHERE clause with more than two fields because the result may be not sorted by the correct field.
Do you have any idea how to do the data model to reach this requirement?

Thank you in advance,
