Find Replace - With wild cards

[VBFnewcomer]

Hi
I have a small issue.
I'd like to find occurances of square brackets [], or this brackets (), in a word document and check if number or alphabet is immediately preceeding or suffixing it without space and if so insert one space.

Eg. my house[VBF]is in china
This I want to change it to my house [VBF] is in china

Eg. my house(VBF)is in china
This I want to change it to my house (VBF) is in china

yes I used the wild card option in more..
I believe it goes something like this in Find section: [A-Za-z0-9]\(
I get struck up in the Replace section:???????

Thanks in advance...
