Hi,
I have some code to rebuild my ferret indexes but occasionally some
stale documents remain in the index even after rebuilding. The only
way I could find around this is to manually delete the index files
from the filesystem. Here is the code I have for rebuilding one of my
indexes for Gifts:
# delete existing entries
INDEX.size.times {|i| INDEX.delete(i)}
gifts = Gift.find(:all)
if (gifts)
gifts.each do |e|
INDEX << self.to_doc
end
end
INDEX.flush()
Does this look ok? I have verified this behavior on Ferret 0.3.2 and
0.9 on windows.
Thanks,
Tom Davies

Personally, I would just reopen the index with :create => true rather than deleting all the documents but it should still work. I have no idea why stale documents would be remaining in the index. Do you have more than one process writing to the index? Can you narrow this behaviour down to a simple test case? Cheers, Dave
Hi Dave, Only one process is writing to the index in this case. If I can narrow it down to a specific example I will try to roll it into a test case. In the mean time I will try the :create => true and perhaps this may bypass the issue altogether. The reason I was deleting the documents that way was based on one of the How Tos on your Trac wiki. I would give you a specific link but your site seems to be giving 500s at the moment. Perhaps the :create => true syntax should also be listed there? Thanks again.

I''ll check the wiki out when I get it up again. Cheers, Dave
