Package-level declarations

Types

CompressionAlgorithm

enum CompressionAlgorithm : Enum<CompressionAlgorithm>

Compression algorithm used for suffixes of a block of terms.

FieldReader

class FieldReader : Terms

BlockTree's implementation of Terms.

Lucene90BlockTreeTermsReader

class Lucene90BlockTreeTermsReader(postingsReader: PostingsReaderBase, state: SegmentReadState) : FieldsProducer

A block-based terms index and dictionary that assigns terms to variable length blocks according to how they share prefixes. The terms index is a prefix trie whose leaves are term blocks. The advantage of this approach is that seekExact is often able to determine a term cannot exist without doing any IO, and intersection with Automata is very fast. Note that this terms dictionary has its own fixed terms index (ie, it does not support a pluggable terms index implementation).

Lucene90BlockTreeTermsWriter

class Lucene90BlockTreeTermsWriter(state: SegmentWriteState, postingsWriter: PostingsWriterBase, minItemsInBlock: Int, maxItemsInBlock: Int, version: Int) : FieldsConsumer

Block-based terms index and dictionary writer.

SegmentTermsEnum

class SegmentTermsEnum(val fr: FieldReader) : BaseTermsEnum

Iterates through terms in this field.

SegmentTermsEnumFrame

class SegmentTermsEnumFrame(ste: SegmentTermsEnum, val ord: Int)

Stats

class Stats

BlockTree statistics for a single field returned by FieldReader.getStats.
