IndexQuery represents the most primitive form of index querying. Instances of this object should be created by QueryResolvers and cached in Query instances.
com.thinkaurelius.titan.diskstorage.indexing.IndexQuery
An external index query executed on an {@link IndexProvider}.
A query is comprised of the store identifier against which the query ought to be executed and a query condition which defines which entries match the query. @author Matthias Broecheler (me@matthiasb.com)
