plainto_tsquery ANDs all terms, so queries like "teenager coffee
instagram" return 0 results when any single term is missing from the
tsvector. Switch to to_tsquery with OR-joined terms so tasks matching
any keyword are returned, ranked by relevance. Sanitize input with
a whitelist (letters, digits, hyphens, underscores) to prevent
tsquery syntax injection.
