guile-xapian 0.4.0 released

[Arun Isaac]

Hi all,

guile-xapian 0.4.0 has been released.

guile-xapian provides Guile bindings for Xapian[1], a search engine
library used in popular applications such as the notmuch email
system. Xapian is a highly adaptable toolkit which allows developers to
easily add advanced indexing and search facilities to their own
applications. It has built-in support for several families of weighting
models and also supports a rich set of boolean query operators.

Please find links to the project home page and tarball below. The
changes in this release are described in the NEWS file in the tarball.

Congrats!
I'm not familiar with Xapian, is it possible to do similar things as
VectorDB?

Best regards.

Hi,

Thanks, Nala!

I am not very familiar with VectorDB. From what I can tell, Xapian and
VectorDB seem to have similar application areas, but Xapian takes a lot
simpler and more traditional approach. You can find a description of the
theory behind Xapian at https://xapian.org/docs/intro_ir.html

Regards,
Arun

Xapian cannot directly be used to build a vector database.  (I use
the pg_vector extension to postgresql for that purpose.)

Xapian creates a more traditional index for finding matching documents
with optimizations for full text and boolean searches.

Ricardo!
Thanks for the explanation. It's clear to me now.

Best regards.

Cool!  That’s nice.

It’s a motivation for resuming [1] as a Guix extension ;-)

Ah, I hadn't thought of xapian search as a Guix extension. Nice idea!

I'm happy to mentor someone if they are interested in such a project.
