> When we enable prefix-based fuzzy-join and apply the multi-way fuzzy-join ( > 2),
the system generates an out-of-memory exception. 
> Since a fuzzy-join is created using 30-40 lines of AQL codes and this AQL is translated
into massive number of operators (more than 200 operators in the plan for a 3-way fuzzy join),
it could generate out-of-memory exception.
