Modifier and Type | Method and Description |
---|---|
int |
docFreq()
Returns the number of documents containing the current
term.
|
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. |
void |
reset() |
TermsEnum.SeekStatus |
seekCeil(BytesRef text)
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).

Returns the resulting BytesRef

if the end of
the iterator is reached. The returned BytesRef may be re-used across calls
to next. After this method returns null, do not call it again: the results

PostingsEnum
for the current term, with
control over whether freqs, positions, offsets or payloads
are required. Do not call this when the enum is
unpositioned. This method will not return null.
NOTE: the returned iterator may return deleted documents, so
deleted documents have to be checked on top of the PostingsEnum
.
