public final class MultiTerms extends Terms
EMPTY_ARRAY
Constructor and Description 

MultiTerms(Terms[] subs,
ReaderSlice[] subSlices)
Sole constructor.

Modifier and Type  Method and Description 

int 
getDocCount()
Returns the number of documents that have at least one
term for this field, or 1 if this measure isn't
stored by the codec.

BytesRef 
getMax()
Returns the largest term (in lexicographic order) in the field.

BytesRef 
getMin()
Returns the smallest term (in lexicographic order) in the field.

ReaderSlice[] 
getSubSlices()
Expert: returns pointers to the subreaders corresponding to the Terms being merged.

Terms[] 
getSubTerms()
Expert: returns the Terms being merged.

long 
getSumDocFreq()
Returns the sum of
TermsEnum.docFreq() for
all terms in this field, or 1 if this measure isn't
stored by the codec. 
long 
getSumTotalTermFreq()
Returns the sum of
TermsEnum.totalTermFreq() for
all terms in this field, or 1 if this measure isn't
stored by the codec (or if this fields omits term freq
and positions). 
boolean 
hasFreqs()
Returns true if documents in this field store
perdocument 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.

. 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.
NOTE: the returned TermsEnum cannot seek
.NOTE: the terms dictionary is free to
return arbitrary terms as long as the resulted visited
docs is the same. E.g., BlockTreeTermsWriter
creates autoprefix terms during indexing to reduce the
number of terms visited.
