How do i use querybuilder.json within AEM to return similar searches?

[Community_Admin]

Can querybuilder.json return a similar search?  That is if I use

querybuilder.json?fulltext=walnt

I'd like to get the results for "walnut".  What predicate should I use?

the underling search used by cq5 is lucene search, think for this we need to make changes in lucene index configuration, don't think cq5 has any specific predicator for the fuzzy searches

HI aklimets, and all. 

I want to search for assets in the whole Dam just excluding a folder(read expired folder). how can i achieve it.. 

i can not do it by using "jar:content/cq:parent path" , because actually I am moving assets to expired folder by a function after query. and i want to exclude this folder for the same(coz moving to same folder 2nd time giving me error). 

so how can i achieve it,

or if is there any property which will change when i'll move a asset to some folder. (2nd option)

please help.
