Class CompositeJoinQuery

  • All Implemented Interfaces:
    QueryParameters, LocaleAware, java.io.Serializable, java.lang.Cloneable
    public final class CompositeJoinQuery
extends Query
    Join query for querying "composite" document that consists of multiple documents.

    A composite document consists of a root document and child documents from one or more clauses. The search query will be evaluated against these documents as if they were a single document. For instance, for a search query of AND(a, b), the composite document will match if "a" is in the root and/or child document and "b" is in the root and/or child document.

    NOTE: the "from" query should specify a one to many or a one to one join to the clauses.
