I'm getting some results that I don't understand from a search.
The code, based on the tutorial, and the results are below.
Everything makes sense to me, except the results for
the 'title:"Some"' query. I would think that it should
match the first two documents, but not the third.
What am I missing here?
Thanks for any help!
--- code -----------------------------------------------------
require 'ferret'
def query(index, query_str)
puts("Query '#{query_str}'...")
index.search_each(query_str) do |id, score|
puts(" id=#{id} score=#{score} uid=#{index[id][:uid]}
title='#{index[id][:title]}'")
end
end
index = Ferret::Index::Index.new
index << {:uid => 'one', :title => 'Some Title', :content => 'my first text'}
index << {:uid => 'two', :title => 'Some Title', :content => 'some second
content'}
index << {:uid => 'three', :title => 'Other Title', :content => 'my third text'}
query(index, 'content:"text"')
query(index, 'content:"some"')
query(index, 'title:"Some"')
query(index, 'title:"Title"')
query(index, 'uid:"two"')
--- results ---------------------------------------
