tin.score(ctid [, dense_ratio [, k1 [, b [, term_add [, term_replace]]]]])
tin.score(tid, real, real, real, text[], text[]) → real
Returns the BM25 relevance of the current row, leaving out dense terms. See Scoring.
tin.full_score(ctid [, k1, b])
tin.full_score(tid) → realtin.full_score(tid, real, real) → real
Returns the BM25 relevance of the current row with every query term kept in the sum. See Scoring.
tin.max_score(ctid)
tin.max_score(tid) → real
Returns the highest score among the query’s matches. The value is the same on every row. See Scoring.
tin.score_inspect(index, query [, dense_ratio [, term_add [, term_replace]]])
tin.score_inspect(regclass, text, real, text[], text[]) → setof (term text, weight real)
Returns the terms a tin.score call with the same arguments would score, with their boost weights. See Scoring.
tin.highlight(text [, begin_tag [, end_tag [, query]]])
tin.highlight(text, text, text, text) → text
Returns the document text with matched spans wrapped in tags. See Highlighting.
tin.highlight_ansi(text [, wrap_to [, query]])
tin.highlight_ansi(text, integer, text) → text
Returns the document text with matched spans in ANSI colors. See Highlighting.
tin.tokenize(text [, …])
tin.tokenize(text) → setof text
Returns the tokens the analysis pipeline produces for a string. Optional named arguments match the index tokenization options and use the same defaults (tokenizer, case_folding, accent_folding, long_tokens, max_token_bytes, graphemes, position_gaps). Useful when debugging why a query does or does not match.
tin.maybe_quote(text)
tin.maybe_quote(text) → text
Quotes a term for safe use inside a TINQL string when it would otherwise be parsed as a keyword or special form.
tin.fsck(index [, heapcheck])
tin.fsck(regclass, boolean) → setof record
Runs a read-only structural check of a TIN index. An empty result means the index passed. It never writes or repairs. Rebuild with REINDEX. Requires ownership of the index.
