Class MoreLikeThisQuery

A simple wrapper for MoreLikeThis for use in scenarios where a Lucene.Net.Search.Query object is required eg in custom QueryParser extensions. At query.Rewrite() time the reader is used to construct the actual MoreLikeThis object and obtain the real Lucene.Net.Search.Query object.

Methods

Equals(object)

Determines whether the specified object is equal to the current object.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
object	obj	The object to compare with the current object.

Returns

Type	Description
bool	true if the specified object is equal to the current object; otherwise, false.

Overrides

Query.Equals(object)

GetHashCode()
