Parameterizing Queries in Solr and Elasticsearch

We all know how good it is to have abstraction layers in software we create. We tend to abstract implementation from the method contracts using interfaces, we use n-tier architectures so that we can abstract and divide different system layers from each other. This is very good – when we change one piece, we don’t need to touch the other parts that only knew about method contracts, API’s, etc. Why not do the same with search queries? Can we even do that in Elasticsearch and Solr? We can and I’ll show you how to do that.
