search for: xapianqueryparser

Hello, Thanks Olly , by following to your suggestion I could do the indexing in the CSV file while the search results retrieved from the Postgres and it's working fine. [ I am using the Xapian PHP-binding to index and search.] How could I enable the WILDCARDS in it ? I followed with the online manual which says it is disabled by default there given some method to enable but I am not

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

It's `XapianQuery::OP_AND`, which was also the correct name in the PHP7 bindings. Looks like `Query_OP_AND` used to happen to work due to how SWIG implemented PHP7 wrappers, but it isn't what we intended people to be using. Cheers, Olly

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)...

I've now uploaded Xapian 1.0.1, which you can download from the usual place: http://www.xapian.org/download.php This release mainly comprises bug fixes and performance improvements. The "simple" examples (for both C++ and the bindings) have also been overhauled and now use the QueryParser and TermGenerator classes, which makes for simpler examples and should better reflect

An answer would be to periodically clean the spellings table (hum... can we iterate over them ?) and to re-index all the documents, but it is not very convenient... Any thought? 4. QueryParser tolerance, reporting query errors It seems that XapianQueryParser is very tolerant: if I parse a 'bad' query (e.g. unmatched brackets, unmatched quotes, nonexistent field name...), it will ignore the error and produce a query. I imagine that this is 'by design' and this is probably the best approach for most users, but I have many cases where i...
