This is my code: db = xapian.Database(path/to/database) enquire = xapian.Enquire stemmer = xapian.Stem(<supported language>)

This is my code:

db = xapian.Database(path/to/database)
enquire = xapian.Enquire
stemmer = xapian.Stem(<supported language>)
query_parser = xapian.QueryParser()
query_parser.set_database(db)
query_parser.set_stemmer(stemmer)
query_parser.set_default_op(xapian.query.OP_OR)
xapian_flags = xapian.QueryParser.FLAG_BOOLEAN | xapian.QueryParser.FLAG_SYNONYM | xapian.QueryParser.FLAG_LOVEHATE
query = query_parser.parse_query('"this exact phrase"', xapian_flags)
enquiry.set_query(query)

This isn’t matching “this exact phrase” (I am able to achieve pretty much everything but exact matches). Note that I’ve included the double quotes mentioned in the documentation. Is there a way of achieving this?

    By explicitly setting the flags to the query parser you override the default of FLAG_PHRASE | FLAG_LOVEHATE | FLAG_BOOLEAN. What you’ve done therefore is to turn on synonym support but turn off phrase searching, which is what the double quotes relies on.

    Note that phrase searching isn’t strictly the same as exact matching, although without more context it’s difficult to advise if this is the wrong approach to take for your situation.
