hey ,

am looking for xapian syntax to do a range search

in my code i have

class Table \< AR  
acts\_as\_xapian :texts =\> [:title],  
:values =\> [[ :left, 0, “left”, :number  
],[:right, 1, “right”, :number] ],  
:terms =\> [ [: left, ‘L’,  
“left”],[:right, ‘R’, “right”]]  
end

and when a launch the following search in console i have an execption

ActsAsXapian::Search.new([Table], ‘left:1…100 AND right:30…200’,  
:limit =\> 100000).result

exception :
