[Xapian-discuss] searching on individual fields

[james cauwelier]

Hi all,


I am using xapian to search a products database of a website (currently 382
000 products).  I am able to build an index and query it.  I was also able
to index separate fields, but I can't find how to combine different parsed
query strings in PHP:

// construct query
$fields = array ('title', 'publisher', 'category', 'subcategory',
'subsubcategory');
$query = array();
foreach ($fields as $field_name) {
    $parser = new XapianQueryParser ();
    $parser->set_stemmer ($stemmer);
    $parser->set_database ($database);
    $parser->set_stemming_strategy (XapianQueryParser::STEM_ALL, null,
'X'.strtoupper($field_name));
    $query[] = '('.$parser->parse_query ($form[$field_name], null,
'X'.strtoupper($field_name)).')';
}
$query = implode (' AND ', $query);

I have different fields which have each a label, for example XTITLE for the
field 'title'.  I use $parser->set_stemming_strategy() to use the correct
labels for these fields, but I seem to make a mistake with the second
argument for this function.  How do I set this FLAG in PHP?  Can I set
multiple?  Do I have to set a flag?  Can I set all flags?
I looked at the API, but I don't seem to find the answer.

Can somebody help me with this?

Thanks,
James Cauwelier
