Searching untokenized fields

Ruby Apps Ferret
#1

Hi …

I tried to exclude certain objects from my search, by adding appropriate
term queries …

i = Ferret::Index::Index.new
i.field_infos.add_field(:type, :index => :untokenized, :term_vector =>
:no)
i << {:type => “Movie”, :name => “Indiana” }
i << {:type => “Movie”, :name => “Forrest” }
i << {:type => “People”, :name => “Forrest” }

now searching for forrest should give 2 results…

i.search_each(“forrest”) do end
=> 2

now i would like to exclude the movie, so i tried to do this:

i.search_each(“forrest AND NOT type:movie”) do end
=> 2

i.search_each(“forrest AND NOT type:Movie”) do end
=> 2

So how to exclude objects with a certain untokenized value in it? having
the field tokenized works great …

This is happening because in this case the QueryParser is downcasing
“Movie”, even though it remained in uppercase in the index. You need
to give the QueryParser a specialized Analyzer that won’t analyze
untokenized fields. This is will be automated in the next version of
Ferret: 0.10.7 for the Index class.
