How to get the count of matching documents
I''m trying to generate a rails pagination helper for some ferret
search results, and I need to know how many total matches there are to
my search query. I don''t see an obvious way of finding this. Any
help would be appreciated.
Thanks,

Ordering results by something other than relevance
Along with the contents of the documents in my index, I have stored
the date they were added. I want to search for keywords in the index
but have the results be sorted by their date rather than their
relevance to the keywords. How would I do this in ferret?
Thanks,
Carl

svn problems
I can consistently segfault the 0.10.4 gem, so I''m trying to get the
subversion version working with hopes towards tracking the problem down.
I have a fresh SVN checkout but:
a) the version (in ferret.rb) claims to be 0.9.6; and
b) Ferret::Index::FieldInfos and a couple other classes are missing at
run time. It looks like this is because they''re not exported in the C

Cannot delete for id of type Array
Hello list,
I have a little weird error when deleting documents from the index.
I''m using the following code.
ferret_index = Ferret::Index::Index.new(:path => FERRET_INDEX_PATH)
query = Ferret::Search::TermQuery.new(:fk_file_id, "#{_fk_file_id}")
ferret_index.search_each(query) do | id |
ferret_index.delete(id)
end
And I get the following error

No matches
The following script creates a search index and then searches it. I get
no results? Where am I going wrong?
Thanks.

Confusing lock problem in rails
I have a model class in rails that has a class variable that is a
ferret index. For some reason, the methods in my class that refer to
the class variable are getting lock conflicts. Can anybody see any
obvious reason why? I notice that it keeps leaving a lock file in the
index directory. I thought auto_flush was supposed to remove the lock
automatically after every operation. Is there

Is it possible to highlight search keywords in results?
I''m wondering if ferret has any built-in search/replace mechanism that
I might be able to use to highlight the query data in each search
result. The reason I think this would be a good idea is that I could
end up having to practically duplicate the ferret query parser just to
interpret the query so that I can figure out how to highlight the
keywords in the search results. Just in case

How to do case-sensitive searches
Forgive me if this topic has already been discussed on the list. I
googled but couldn''t find much. I''d like to search through text for
US state abbreviations that are written in capitals. What is the best
way to do this? I read somewhere that tokenized fields are stored in
the index in lowercase, so I am concerned that I will lose precision.
What is the best way to store a

undefined method `add'' for Ferret::Search::BooleanQuery
Up to now in my ferret development I have been using simple
single-word strings as my search queries. I just now am trying to
increase the complexity of my queries. When I was passing a single
word with no spaces in my index searches, like so:
count = index.search_each(''testing'') do |d, s|
...
end
everything worked fine. But now when I do something like this:

Searching untokenized fields
Hi ..
I tried to exclude certain objects from my search, by adding appropriate
term queries ..
i = Ferret::Index::Index.new

i << {:type => "Movie", :name => "Indiana" }

issues with : in the content
Hi,
I''ve discovered ferret and aaf this evening, I''ve just done some tests
and it seems perfect for my needs.
I''m indexing text data (title, description, etc) and also ethernet
hardware addresses (MAC).
Sorry if that sounds trivial but I can''t find the way to correctly
index and achieve correct searches on MAC addresses.
If I do something like this:

Query Objects vs. Query Strings
Hi ..
I tried to build some query objects to get some documents from my
index.. without success.. Is something wrong here?
q = Ferret::Search::BooleanQuery.new
q1 = Ferret::Search::TermQuery.new(:type, "movie")
q2 = Ferret::Search::TermQuery.new(:name, "Indiana")
q.add_query(q1, :should)
q.add_query(q2, :should)

Confused about Search Results
Hi everyone,
I''m pretty new to Lucene and Ferret, so I feel that this is most likely
myself not completely understanding the correct way to do this. I haved
indexed ~2200 text files (of various sizes), and I am now running
searches on the index to get a feel for Lucene and Ferret.
In my first program, which is using Lucene I search for ''influenza'' and
get the

Reverse sorting
I am getting strange results when I reverse sort a query. I am sorting
by date, but it doesn''t seem to be related to dates (I have tried just
integers). I also paginate the results. Items in the result set are
sometimes duplicated and the not ordered at all. When I try a
non-reverse sort I don''t see duplicates and the ordering is correct. Any
ideas what is going on? Thanks

Searcher do not work or I do not work
Hi.
I want to learn more about ferret. So I downloaded ferret-0.10.14 and
write a simple test script
Only query = TermQuery.new(:content, ''program'') gives result.
If I change ''program'' with ''Good'' or ''Extra'' -> no result
and searching on (:title, ''Ruby'') -> no result

Index returning ids that are one less than they should be
I''m saving records to an index like so:
index << {:id => id, :email => email, :contents => contents, :date => found_on}
In debugging my code, it appears that whatever I set a record''s id to,
when I find that record in a search, it returns the id minus 1, so if
the first record I store in my database has an id of one and I store
its counterpart in my index,

More sorting problems with untokenized index
I''m having problems sorting on untokenized fields. I have one field that
sorts fine, but there are others that seem to sort on a different field.
Here''s the index description:

find_by_contents not returning SearchResults?

Which analyzer to use
Lucene''s standard analyzer splits words separater with underscores.
Ferret doesn''t do this. For example, if I create an index with only
document ''test_case'' and search for ''case'' it doesn''t find anything.
Lucene on the other hand finds it. The same story goes for words
separated by colons.
Which analyzer should I use to emulate

adding a custom filter to the query
Hi all,
I''m trying to figure out how to add a filter into a search. I''ve
created the filter, basically copying the location filter from
http://blog.tourb.us/archives/ferret-and-location-based-searches. But
when I try to call Index.search and pass the filter in a hash with the
key :filter, I get back that it is expecting type Data, and so I''m at
a loss to figure out
