search for: set_default_op

Hi all, I'm sorry to bother you guys with such a rookie question. I tried to change the default boolean operator by editing the file queryparser.h like this: void set_default_op(Query::op OP_AND); However, after rebuilding I tested it with the query "grad school" and it still worked with the OP_OR as default, like this: Parsed query is: Xapian::Query((Zgrad:(pos=1) OR Zschool:(pos=2))) Could somebody give me any clue about this? Is there any other file in the...

...pianWritableDatabase; Thank you very much. This then (because of course) led to some more things needing tidying up and I've run into something I can't work out while trying to update previously-worked-in-php7 code in the actual file I'm trying to update $this->queryparser->set_default_op(Query_OP_AND); ...leads to "Undefined constant "App\Helpers\Query_OP_AND" because... another namespace issue? ("OP_AND" and "XapianQueryParser::OP_AND" are also not accepted.) jh

Salve, Thank you very much for your kind answer. Spelling correction works very well now. I have just one more question. I am using Xapian::QueryParser() to create the Query. The flags are: FLAG_PHRASE | FLAG_LOVEHATE | FLAG_WILDCARD If I search, lets say for "king queen" (without quotes), I get all documents with either "king" or "queen". Is there a chance to

I use the QueryParser::parse_query() method but I see it uses "OR" by default between words? Is there a way to make it use "AND" instead? I see there are flags I can pass to the parse_query() method but none seems to allow a switch from OR to AND. I would like to do that without having to write my own query parser. Everything else is fine with the QueryParser parsing, for

You need to tell PHP to look in the root namespace, e.g.: $test = new \XapianWritableDatabase('searchdb'); Another

Hello, I'm wondering about how the QueryParser parses a query containing an "alias" when the default operator is OP_AND (by "alias", I mean a search field mapped to multiple term prefixes). With the following php code : <?php $parser=new XapianQueryParser(); $parser->set_default_op(XapianQuery::OP_AND); $parser->add_prefix('alias', 'AUT1:'); $parser->add_prefix('alias', 'AUT2:'); echo $parser->parse_query('alias:(john smith)')->get_description(); ?> I get: Xapian::Query(((AUT1:john:(pos=1) OR AUT2:john:(pos=1)) AND (AUT...
