Class MaxClauseCountQueryVisitor

java.lang.Object

org.apache.lucene.search.QueryVisitor

org.elasticsearch.search.internal.MaxClauseCountQueryVisitor

public final class MaxClauseCountQueryVisitor
extends org.apache.lucene.search.QueryVisitor

QueryVisitor that counts visited clauses and throws IndexSearcher.TooManyNestedClauses when the configured maximum is exceeded.

IndexOrDocValuesQuery is treated as a single clause and its inner queries are ignored, and IndexSortSortedNumericDocValuesRangeQuery is skipped so only the fallback query is counted.
