BlockTermsReader |
Handles a terms dict, but decouples all details of
doc/freqs/positions reading to an instance of
PostingsReaderBase . |
BlockTermsWriter |
Writes terms dict, block-encoding (column stride) each
term's metadata for each set of terms between two
index terms.
|
FixedGapTermsIndexReader |
TermsIndexReader for simple every Nth terms indexes.
|
FixedGapTermsIndexWriter |
Selects every Nth term as and index term, and hold term
bytes (mostly) fully expanded in memory.
|
TermsIndexReaderBase |
BlockTermsReader interacts with an instance of this class
to manage its terms index. |
TermsIndexReaderBase.FieldIndexEnum |
Similar to TermsEnum, except, the only "metadata" it
reports for a given indexed term is the long fileOffset
into the main terms dictionary file.
|
TermsIndexWriterBase |
Base class for terms index implementations to plug
into
BlockTermsWriter . |
VariableGapTermsIndexReader | |
VariableGapTermsIndexWriter |
Selects index terms according to provided pluggable
VariableGapTermsIndexWriter.IndexTermSelector , and stores them in a prefix trie that's
loaded entirely in RAM stored as an FST. |
VariableGapTermsIndexWriter.EveryNOrDocFreqTermSelector |
Sets an index term when docFreq >= docFreqThresh, or
every interval terms.
|
VariableGapTermsIndexWriter.EveryNTermSelector |
Same policy as
FixedGapTermsIndexWriter |
