[Sputnik-list] Who know luasoket and lpack ? (For Sphinx full text search)

[pierre pracht]

Sphinx is a full-text search engine. http://sphinxsearch.com/

I was tring to convert  api/sphinxapi.py to lua
(See in sphinx-0.9.8-svn-r1112.tar.gz (544 KB) )

I managed to send query correctly : Sphinx:Query
But I get nuts with Sphinx:GetReponse

lpack use a different notation than pack in python and I haven't  
really understood it.
I get some doubt that I can do : sock:receive(8) with luasocket.

If someone has some insight on those modules ?

I post here in case someone would take on.
Using sphinx may interest you.

Personally I give up.

-- get and check response packet from searchd server
