Ferret talk - May 2007 - return ONLY total_hits without querying from real database

Hey guys,

I know I can run search(q).total_hits, but if I try to put :limit=>0 it
gives me an error. I don''t want it actually query any of the results, I
just want it to tell me how many total_hits I would have if I wanted to
search it.

How can I do this?

Model.total_hits(query)

Hi Jens,

I don''t have that method, could it have something to do with the fact 
that Im using

Ferret::MixinActs::ARFerret

Do I need to upgrade or can I just add that function?

I''m not sure what you''re using there - I was thinking
it''s
acts_as_ferret because of the method name.

Here is what acts_as_ferret.rb says, maybe this is a really old version 
or something.

# The Rails ActiveRecord Ferret Mixin.
#
# This mixin adds full text search capabilities to any Rails model.
#
# The current version emerged from on the original acts_as_ferret plugin 
done by
# Kasper Weibel and a modified version done by Thomas Lockney, which 
both can be
# found on the Ferret Wiki: 
http://ferret.davebalmain.com/trac/wiki/FerretOnRails.
#
# basic usage:
# include the following in your model class (specifiying the fields you 
want to get indexed):
# acts_as_ferret :fields => [ ''title'',
''description'' ]
#
# now you can use ModelClass.find_by_contents(query) to find instances 
of your model
# whose indexed fields match a given query. All query terms are required 
by default, but
# explicit OR queries are possible. This differs from the ferret 
default, but imho is the more
# often needed/expected behaviour (more query terms result in less 
results).

yes, seems so. You should upgrade to the current stable version.

Hey Jens,

I upgraded to the latest version. Everything works great, it even 
queries the results more efficiently. Great job!

I don''t see any method for total_hits for multi_search. The 
model.total_hits works fine when you are just searching on one model.

Any idea how to do only total_hits with multi_search?


Also, I added a little fix to multi_search to allow users to include 
associations even if it works on one model but not the other. Here is 
what the code looks like. It currently works great on one-level include 
and somewhat hacky on two-level associations. Maybe you can find some 
use for it?

That was indeed missing. I just committed a fix for this to trunk. now
you can give total_hits additional model classes with the :models
option:

A.total_hits(query, :models => [B, C])
