Hi,

I’m trying to open a Index created by Lucene 1.9.1. I know the index has  
not been  
corrupted, I can browse it with Luke but when I try:  
irb\> Ferret::Index::IndexReader.new("./index’")

I get the following error message:  
Ferret::FileNotFoundError: File Not Found Error occured at \<except.c\>:93  
in xraise  
Error occured in index.c:840 - sis\_find\_segments\_file  
couldn’t find segments file

from (irb):7:in `initialize' from (irb):7:in`new’  
from (irb):7

the segments file is inside ./index but something get wrong.

Help is appreciated 🙂

Ferret::VERSION = 0.11.6

Thanks!

Hi,

as far as I remember compatibility with Lucene indexes has been dropped  
at some point in time (around Ferret versions 0.9.x or maybe even  
earlier).

Cheers,  
Jens
