Ferret talk - Jan 2008 - Escaping special characters :, (, ), [, ], {, }, !, +, ", ~, ^, -, |, <, >, =, *, ?, \

Hello,

I am trying to escape words for searching i.e., "hello". The key here
is that the two L''s on "hello" are actually vertical bars. 
Is there
a special function in Ferret or anywhere for that matter that will do  
the escaping of the Ferret special characters?

Thanks in advance,

Benjamin

Hello,

I am going to answer my own questions...

You can do something like:

def escape_string(str)
	str =
Regexp.escape(item[:word]).gsub(/([:~!<>="])/,''\\\\\1'')
end

At one time there was a function called clean_string in QueryParser  
but it appears to be gone.
