int |
getDocCount()
Returns the number of documents that have at least one
term for this field.
|
BytesRef |
getMax()
Returns the largest term (in lexicographic order) in the field.
|
BytesRef |
getMin()
Returns the smallest term (in lexicographic order) in the field.
|
long |
getSumDocFreq()
Returns the sum of
TermsEnum.docFreq() for
all terms in this field. |
long |
getSumTotalTermFreq()
Returns the sum of
TermsEnum.totalTermFreq() for
all terms in this field. |
boolean |
hasFreqs()
Returns true if documents in this field store
per-document term frequency (
PostingsEnum.freq() ). |
boolean |
hasOffsets()
Returns true if documents in this field store offsets.
|
boolean |
hasPayloads()
Returns true if documents in this field store payloads.
|
boolean |
hasPositions()
Returns true if documents in this field store positions.
|
TermsEnum |
intersect(CompiledAutomaton compiled,
BytesRef startTerm)
Returns a TermsEnum that iterates over all terms and
documents that are accepted by the provided
CompiledAutomaton . |
TermsEnum |
iterator()
Returns an iterator that will step through all
terms.
|
long |
size()
Returns the number of terms for this field, or -1 if this
measure isn't stored by the codec.

CompiledAutomaton
. If the startTerm
is
provided then the returned enum will only return terms
> startTerm
, but you still must call
next() first to get to the first term. Note that the
provided startTerm
must be accepted by
the automaton.
This is an expert low-level API and will only work
for NORMAL
compiled automata. To handle any
compiled automata you should instead use
CompiledAutomaton.getTermsEnum(org.apache.lucene.index.Terms)
instead.
NOTE: the returned TermsEnum cannot seek
