Hello, I'm searching for a good search server solution and are considering the advantages and disadvantages of Elastic Search. I will use RavenDB to store the raw, general data and have heard a lot of good things about RavenDB's searching capabilities... Since I have to use RavenDB to store the data in the first place, is it worth it to combine it with elastic search for more advanced search options? "Percolation" in elastic search is a feature in my application that will be crucial so if I decide to only go for RavenDB I need to know that a equivalent feature does exist. ---

You want to know if RavenDB has a feature analogous to percolation? Wouldn't that be better asked on a RavenDB mailing list? ---

I know very little about RavenDB, so I just looked it up. RavenDB uses Lucene underneath the cover. The RavenDB provides an ORM layer to create queries, but also allows query in the standard Lucene query parser syntax. It is unclear how they achieve faceted search (there are several libraries for Lucene). What is especially unclear is how RavenDB implements sharding for search. Elasticsearch provides several ways to distribute Lucene queries and documents. Are the lucene indices sharded in RavenDB or is it a full-replica. Not sure what the main storage engine is (also Lucene?) Coupling RavenDB with Elasticsearch seems to be an overkill and I would only implement that strategy if I really really really needed a feature (Percolation). Complex architectures require too much work to maintain. Elasticsearch appears to have more features, but it lacks the ORM layer. I would spend time writing my own layer and not writing code around integrating two similar products.
