org.apache.solr.search.GraphTermsQParserPlugin

All Implemented Interfaces:

AutoCloseable, SolrInfoBean, SolrMetricProducer, NamedListInitializedPlugin

public class GraphTermsQParserPlugin
extends QParserPlugin

The GraphTermsQuery builds a disjunction query from a list of terms. The terms are first filtered by the maxDocFreq parameter. This allows graph traversals to skip traversing high frequency nodes which is often desirable from a performance standpoint.

Syntax: {!graphTerms f=field maxDocFreq=10000}term1,term2,term3
