Hi everyone, I’m having trouble with the Index scan() method. When I  
call it, I receive a ‘private method called’ error. Example:

index.scan(‘blah’)  
 → private method `scan’ called for #Ferret::Index::Index:0xb7c15374  
(NoMethodError)

I tried it on the searcher as well:

index.searcher.scan(‘blah’)  
 → private method `scan’ called for #\<Ferret::Search::Searcher:  
0xb7c0161c\> (NoMethodError)

scan() docs:

I’m using ferret-0.11.6.

Can anyone offer any suggestions?

Thanks,

Derek
