Description copied from class:Terms
Returns an iterator that will step through all terms. This method will not return null. -
intersect
Description copied from class:Terms
Returns a TermsEnum that iterates over all terms and documents that are accepted by the providedCompiledAutomaton
. If thestartTerm
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 providedstartTerm
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 useCompiledAutomaton.getTermsEnum(org.apache.lucene.index.Terms)
instead.NOTE: the returned TermsEnum cannot seek.
-
size
public long size()Description copied from class:Terms
Returns the number of terms for this field, or -1 if this measure isn't stored by the codec. Note that, just like other term measures, this measure does not take deleted documents into account. -
getSumTotalTermFreq
public long getSumTotalTermFreq()Description copied from class:Terms
Returns the sum ofTermsEnum.totalTermFreq()
for all terms in this field. Note that, just like other term measures, this measure does not take deleted documents into account.- Specified by:
getSumTotalTermFreq
in classTerms
-
getSumDocFreq
public long getSumDocFreq()Description copied from class:Terms
Returns the sum ofTermsEnum.docFreq()
for all terms in this field. Note that, just like other term measures, this measure does not take deleted documents into account.- Specified by:
getSumDocFreq
in classTerms
-
getDocCount
public int getDocCount()Description copied from class:Terms
Returns the number of documents that have at least one term for this field. Note that, just like other term measures, this measure does not take deleted documents into account.- Specified by:
getDocCount
in classTerms
-
hasFreqs
public boolean hasFreqs()Description copied from class:Terms
Returns true if documents in this field store per-document term frequency (PostingsEnum.freq()
). -
hasOffsets
public boolean hasOffsets()Description copied from class:Terms
Returns true if documents in this field store offsets.- Specified by:
hasOffsets
in classTerms
-
