Description copied from interface: IDocumentMatcher

Adds stop word support. This is typically done by checking if the matchers terms are stop words by calling the IndexedDocument method isStopWord( string ). See TermDocumentMatcher.

Specified by:

isStopWord in interface IDocumentMatcher

Overrides:

isStopWord in class BasicDocumentMatcher

getTermSet

public java.util.Set getTermSet()

returns null because we don't know what the positive terms are - only negative terms!

Specified by:

getTermSet in interface IDocumentMatcher

Overrides:

getTermSet in class BasicDocumentMatcher

getPhraseSet

public java.util.Set getPhraseSet()

Description copied from interface: IDocumentMatcher

returns the list of phrases in all contained PhraseDocumentMatchers

Specified by:

getPhraseSet in interface IDocumentMatcher

Overrides:

getPhraseSet in class BasicDocumentMatcher
