Hi,

I am relatively new with Xapian and also needed this functionality.  Here is
what I found out.

There are two things you have to do:

- When adding a posting, choose the right prefix
- When searching, use these prefixes and maybe add the prefixes to your parser.

By default, a prefix Z is used

Other prefixes:

S for title
A for author
X for custom prefixes

if you want a category prefix, use XCATEGORY as prefix
if you want a price prefix, use XPRICE

// adding the posting on indexing
$xapian_document->add_posting (XCATEGORYbooks, $position, $weight);

// searching for it
$parser->add_prefix ('category', 'XCATEGORY');
$query = $parser->parse_query ('category:books');
