> Do you mean "reduced by 60%" (rather than "reduced to 60%")?
Reduced by 65%, database went form ~9GB to 3.8GB.
I want to mention that I have compiled Xapian with BM25Weight() : k1(10000),
k2(0), k3(0), b(0), min_normlen(0.5) because I need to get documents with
most frequencies at the top.
I also use only add_term with a lot frequencies (based on "pagerank" and
html formatting) and for adding/replacing documents I use the nest
$code= unique id from my mysql database
$doc = Search::Xapian::Document->new();
I can create Xapian database with a few hundreds documents and sent it to
you if you want.
