Search Syntax - Combination of proximity and wildcard/fuzzy search?

[DB]

With our old database (not confluence) we could combine proximity search with wildcards, for example:

rela* <NEAR/5> index*

Now we recently introduced confluence in our office.

In confluence I tried with

"rela* index*"~5 

or

"rela~ index~"~5

but these two didn't work.

Any suggestions? help?
