Hi there,

Is highlighting for range queries supposed to work ?  
It doesn’t work here.

here is an non-working example: (highlighting works when q=“test:2007\*”)

require ‘ferret’  
include Ferret

index = Index::Index.new()  
#index.field\_infos.add\_field(:test, :store =\> :yes, :index =\>  
:untokenized)

i=1  
for a in [“20070505”, “20071230”, “20060920”, “20081111”]  
index \<\< {:id =\> i, :test =\> a}  
i+=1  
end

for q in [ ‘test:( \>= 20070101)’, ‘test:2007\*’,  
Ferret::Search::RangeQuery.new(:test, :\>= =\> “20070101”) ]  
index.search\_each(q) do |id, score|  
puts “Document #{index[id][:test]} found with a score of #{score}”  
highlights = index.highlight(q, id, :field =\> :test, :pre\_tag =\>  
“\033[36m”, :post\_tag =\> “\033[m”)  
puts highlights  
end  
puts “------”  
end

Your test doesn’t work for me, too - looks like highlighting is just not  
yet implemented for RangeQueries…
