Valid Query Formats

tantivy-py supports the query language used in tantivy. Below a few basic query formats are shown:

  • AND and OR conjunctions.
query = index.parse_query('(Old AND Man) OR Stream', ["title", "body"])
(best_score, best_doc_address) = searcher.search(query, 3).hits[0]
best_doc = searcher.doc(best_doc_address)
  • +(includes) and -(excludes) operators.
query = index.parse_query('+Old +Man chef -fished', ["title", "body"])
(best_score, best_doc_address) = searcher.search(query, 3).hits[0]
best_doc = searcher.doc(best_doc_address)

Note: in a query like above, a word with no +/- acts like an OR.

  • phrase search.
query = index.parse_query('"eighty-four days"', ["title", "body"])
(best_score, best_doc_address) = searcher.search(query, 3).hits[0]
best_doc = searcher.doc(best_doc_address)
  • integer search
query = index.parse_query('"eighty-four days"', ["doc_id"])
(best_score, best_doc_address) = searcher.search(query, 3).hits[0]
best_doc = searcher.doc(best_doc_address)

Note: for integer search, the integer field should be indexed.
