Highlighting broken in TRUNK

Ruby Apps Ferret
1

Hello list,

As there is still some large file support bugs in the 0.11.4 release
I had to download the trunk and apply a patch sent in by kyle http://
ferret.davebalmain.com/trac/ticket/215.

The problem is now that the highlighting doesn’t work.

Somehow it combines excerpt_length with num_excerpts so if you have
and excerpt_length of 50 and num_excerpts of 5 and you get only one
hit when searching the excerpts is either the whole text or 50*5 = 250.

So everytime you get a result with less hits than num_excerpts the
highlighting goes crazy.

Comments, Fixes, Patches are all welcome :slight_smile:

Cheers,
Henrik

I’ve had the same problem with the large file patch. I couldn’t figure
out a fix, but I worked around it by trimming the excerpts to the last
150 characters:

   highlights.collect do |excerpt|
     if excerpt.length <= 150
       excerpt
     else
       excerpt[-150..-1]
     end
   end

This is ugly, and it chops up words, but it seems to work.

I wondered if this might have something to do with Ferret’s low-level IO
routines: is_read_u64, os_read_u64, is_read_u32, etc. Maybe the wrong
ones are being used for reading and writing the offsets in the segment
file, now that Kyle’s patch has changed the offsets from type int to
type offset_t.

Thanks for the info. Now I know I’m not the only one experience this
problem. =)
Thanks for code sharing. I’ll probably do something similar until
this is fixed.
It would be nice to get Dave’s input on this but it seems he
disappeared from the face of the earth.

Thanks,
Henrik
