DecodeTSQuery deserializes a serialized TSQuery in on-disk format.

DecodeTSQueryPGBinary deserializes a serialized TSQuery in pgwire format.

DecodeTSVector decodes a tsvector in disk-storage representation from the input byte slice.

DecodeTSVectorPGBinary decodes a tsvector from the input byte slice which is formatted in Postgres binary protocol.

DocumentToTSVector parses an input document into lexemes, removes stop words, stems and normalizes the lexemes, and returns a TSVector annotated with lexeme positions according to a text search configuration passed by name.

EncodeInvertedIndexKey returns the inverted index key for the input lexeme.

EncodeInvertedIndexKeys returns a slice of byte slices, one per inverted index key for the terms in this tsvector.

EncodeTSQuery encodes a tsquery into a serialized representation for on-disk storage.

EncodeTSQueryPGBinary encodes a tsquery into a serialized representation.

EncodeTSVector encodes a tsvector into a serialized representation for on-disk storage.

EncodeTSVectorPGBinary encodes a tsvector into a serialized representation that's identical to Postgres's wire protocol representation.

EvalTSQuery runs the provided TSQuery against the provided TSVector, returning whether or not the query matches the vector.

GetConfigKey returns a config that can be used as a key to look up stemmers and stopwords from an input config value.

ParseTSQuery produces a TSQuery from an input string.

ParseTSVector produces a TSVector from an input string.

PhraseToTSQuery implements the phraseto_tsquery builtin, which lexes an input, performs stopwording and normalization on the tokens, and returns a parsed query, interposing the <-> operator between each token.

PlainToTSQuery implements the plainto_tsquery builtin, which lexes an input, performs stopwording and normalization on the tokens, and returns a parsed query, interposing the & operator between each token.

RandomTSQuery returns a random TSQuery for testing.

RandomTSVector returns a random TSVector for testing.

Rank implements the ts_rank functionality, which ranks a tsvector against a tsquery.

ToTSQuery implements the to_tsquery builtin, which lexes an input, performs stopwording and normalization on the tokens, and returns a parsed query.

TSLexize implements the "dictionary" construct that's exposed via ts_lexize.

TSParse is the function that splits an input text into a list of tokens.

ValidConfig returns an error if the input string is not a supported and valid text search config.

TSQuery represents a tsNode AST root.

TSVector is a sorted list of terms, each of which is a lexeme that might have an associated position within an original document.
