[Xapian-discuss] Seek help with simple writer/search using Perl

[Mark Blythe]

Since Xapian doesn't have any expectations about the data you store in the
document, you can store whatever you like.  It could be a serialized data
structure (using Data::Dumper, JSON, etc), or something more simple like a
delimited string.  In your case, you might store something like:

url|title|description

Then you could retrieve it and fill a hash by doing a simple split:

my %data;
@data{qw(url title description)} = split(/\|/, $document->get_data);
