int |
docFreq()
Returns the number of documents containing the current
term.
|
private void |
grow() |
ImpactsEnum |
impacts(int flags)
Return a
ImpactsEnum . |
BytesRef |
next()
Increments the iteration to the next
BytesRef in the iterator. |
long |
ord()
Returns ordinal position for current term.
|
PostingsEnum |
postings(PostingsEnum reuse,
int flags)
Get
PostingsEnum for the current term, with
control over whether freqs, positions, offsets or payloads
are required. |
TermsEnum.SeekStatus |
seekCeil(BytesRef term)
Seeks to the specified term, if it exists, or to the
next (ceiling) term.
|
void |
seekExact(long ord)
Seeks to the specified term by ordinal (position) as
previously returned by
TermsEnum.ord() . |
BytesRef |
term()
Returns current term.
|
TermState |
termState()
Expert: Returns the TermsEnums internal state to position the TermsEnum
without re-seeking the term dictionary.
|
long |
totalTermFreq()
Returns the total number of occurrences of this term
across all documents (the sum of the freq() for each
doc that has this term).

NOTE: the returned iterator may return deleted documents, so
deleted documents have to be checked on top of the PostingsEnum
