Public Methods

Method Description
Analyzer ( string analyzer ) : MoreLikeThisQueryBuilder

The analyzer that will be used to analyze the text. Defaults to the analyzer associated with the fied.
Boost ( float boost ) : MoreLikeThisQueryBuilder
BoostTerms ( float boostTerms ) : MoreLikeThisQueryBuilder

Sets the boost factor to use when boosting terms. Defaults to 1.
LikeText ( string likeText ) : MoreLikeThisQueryBuilder

The text to use in order to find documents that are "like" this.
MaxDocFreq ( int maxDocFreq ) : MoreLikeThisQueryBuilder

Set the maximum frequency in which words may still appear. Words that appear in more than this many docs will be ignored. Defaults to unbounded.
MaxQueryTerms ( int maxQueryTerms ) : MoreLikeThisQueryBuilder

Sets the maximum number of query terms that will be included in any generated query. Defaults to 25.
MaxWordLen ( int maxWordLen ) : MoreLikeThisQueryBuilder

Sets the maximum word length above which words will be ignored. Defaults to unbounded (0).
MinDocFreq ( int minDocFreq ) : MoreLikeThisQueryBuilder

Sets the frequency at which words will be ignored which do not occur in at least this many docs. Defaults to 5.
MinTermFreq ( int minTermFreq ) : MoreLikeThisQueryBuilder

The frequency below which terms will be ignored in the source doc. The default frequency is 2.
MinWordLen ( int minWordLen ) : MoreLikeThisQueryBuilder

Sets the minimum word length below which words will be ignored. Defaults to 0.
MoreLikeThisQueryBuilder ( ) : System

Constructs a new more like this query which uses the "_all" field.
PercentTermsToMatch ( float percentTermsToMatch ) : MoreLikeThisQueryBuilder

The percentage of terms to match. Defaults to 0.3.
StopWords ( ) : MoreLikeThisQueryBuilder

Set the set of stopwords.

Any word in this set is considered "uninteresting" and ignored. Even if your Analyzer allows stopwords, you might want to tell the MoreLikeThis code to ignore them, as for the purposes of document similarity it seems reasonable to assume that "a stop word is never interesting"
ToJsonObject ( ) : object
ToString ( ) : string
