VariableGapTermsIndexWriter

class VariableGapTermsIndexWriter(state: SegmentWriteState, policy: VariableGapTermsIndexWriter.IndexTermSelector) : TermsIndexWriterBase

Selects index terms according to provided pluggable IndexTermSelector, and stores them in a prefix trie that's loaded entirely in RAM stored as an FST. This terms index only supports unsigned byte term sort order (unicode codepoint order when the bytes are UTF8).

Types

EveryNOrDocFreqTermSelector

class EveryNOrDocFreqTermSelector(docFreqThresh: Int, interval: Int) : VariableGapTermsIndexWriter.IndexTermSelector

Sets an index term when docFreq >= docFreqThresh, or every interval terms. This should reduce seek time to high docFreq terms.

EveryNTermSelector

class EveryNTermSelector(interval: Int) : VariableGapTermsIndexWriter.IndexTermSelector

Same policy as FixedGapTermsIndexWriter

IndexTermSelector

abstract class IndexTermSelector

Hook for selecting which terms should be placed in the terms index.
