Yes, I use Ferret whenever I need some kind of search for a site or
application I’m working on. Usually these are full text searches for
product catalogs and/or html content - not really large scale, at most
around 10000 documents. Most recent example is www.fahrrad-xxl.de.
We also use Ferret + aaf in a knowledge management system I’m working
on for xscio AG (xscio.de).
- What is the maximum number of documents we can index with ferret?
Has some one informations about that.
I have no idea whether there is an upper limit for the number the
documents other than the maximum value a Ruby Fixnum instance can
- What is the best way to access a very huge Ferret Index? May we
distribute it on several machines or not?
Afair there’s no way to distribute an index across multiple machines
built into Ferret. You could do the distribution yourself of course by
clustering your data and distributing across several independent
ferret indexes. Downside is that search result scores from different
indexes aren’t directly comparable.
By the way, can Ferret read Solr indexes as they are both clones of
Ferret isn’t really index compatible with Lucene anymore, it uses a
slightly different index format mostly due to differences in the
representation of utf8 values, but I think there were other changes,
Oh, and Solr also isn’t a clone of Lucene, it’s a search server that
internally uses the Lucene library.
