public abstract class SearchServerQuery
extends Object

An abstract super class for query objects. For each SearchServerCommand, one such object is given to form the central element of the request, the query itself. This does not include the number of documents to return, faceting and such.

The classes extending this class will be inspired by the ElasticSearch query DSL (http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl.html) since, at the time of writing, ElasticSearch is the employed search server. Also, the ElasticSearch query DSL is well structured following an object property approach, which is easily represented as Java objects, where the corresponding Solr queries consist of different, not always easy to understand, elements as the query itself and local parameters (https://wiki.apache.org/solr/LocalParams). Thus, when using another search server, e.g. Solr, those queries must be translated in the Solr search component.
