TextIndexBuilder

class TextIndexBuilder

Parameters of a full-text index.

Constructors

TextIndexBuilder

constructor()

Properties

asciiFolding

var asciiFolding: Boolean?

Fold accented characters to ASCII, so "ação" and "acao" are the same token.

enableHnsw

var enableHnsw: Boolean?

Build the extra HNSW links for this field, so a filtered search over it reads the matching points rather than walking the collection. Needs payloadM above zero on the collection's HNSW config.

lowercase

var lowercase: Boolean?

Lowercase every token, making matching case-insensitive. Defaults to true on the server.

maxTokenLen

var maxTokenLen: Int?

Drop tokens longer than this.

memory

var memory: Memory?

Memory placement of the index. Overrides onDisk when both are set.

minTokenLen

var minTokenLen: Int?

Drop tokens shorter than this.

onDisk

var onDisk: Boolean?

Keep the index on disk instead of in RAM.

phraseMatching

var phraseMatching: Boolean?

Store token positions so matchPhrase works. See PayloadIndexParams.Text.phraseMatching.

stemmer

var stemmer: StemmingAlgorithm?

Reduce tokens to a stem, so "running" matches "run". The server's default is no stemming, and it is the right default for a field of identifiers or product codes. See StemmingAlgorithm.

tokenizer

var tokenizer: Tokenizer?

How a value is split into tokens. The server's default is Tokenizer.WORD.
