Method Detail
-
getMin
public BytesRef getMin() throws java.io.IOException
Description copied from class:Terms
Returns the smallest term (in lexicographic order) in the field. Note that, just like other term measures, this measure does not take deleted documents into account. This returns null when there are no terms.
-
getMax
public BytesRef getMax() throws java.io.IOException
Description copied from class:Terms
Returns the largest term (in lexicographic order) in the field. Note that, just like other term measures, this measure does not take deleted documents into account. This returns null when there are no terms.
-
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
-
hasPositions
public boolean hasPositions()
Description copied from class:Terms
Returns true if documents in this field store positions.- Specified by:
hasPositions
in classTerms
-
hasPayloads
public boolean hasPayloads()
Description copied from class:Terms
Returns true if documents in this field store payloads.- Specified by:
hasPayloads
in classTerms
-
iterator
public TermsEnum iterator() throws java.io.IOException
Description copied from class:Terms
Returns an iterator that will step through all terms. This method will not return null.
-
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:
