 I don't need it for other objects I already have. But, as a bonus, it 
would not be so bad, so it is not really a problem :)

 Why? I usually gave it the name of the form input I want to index...

 I though just to index the new objects... but I miss the picture maybe, 
what is so important with the names "NormalizedSearchableText" and 
"SearchableText"?

 How? :-? Maybe I miss some overloading or acquisition?

 Ok

 And how do I add it? Just creating the python script and using 
acquisition? How does it work? :P
