Description
Class Summary | |
---|---|
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 | See VariableGapTermsIndexWriter |
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 |
VariableGapTermsIndexWriter.IndexTermSelector | Hook for selecting which terms should be placed in the terms index. |
Pluggable term index / block terms dictionary implementations.
