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. |
TermsEnum.SeekStatus |
seekCeil(BytesRef text)
Seeks to the specified term, if it exists, or to the
next (ceiling) term.
|
boolean |
seekExact(BytesRef text)
Attempts to seek to the exact term, returning true if the term is found.
|
void |
seekExact(long ord)
Seeks to the specified term by ordinal (position) as
previously returned by
TermsEnum.ord() . |
BytesRef |
term()
Returns current term.
|
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).

PostingsEnum
for the current term, with
control over whether freqs, positions, offsets or payloads
are required. Do not call this when the enum is

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