How to make custom search form with views and taxonomy?

Hi!

I have made profile content type for users where they can write their skills and professions. There's three kind of fields: interests, skills and professions. Now I need to make search form where the other users can search for some of these three kinds with free text.

So I need select field, where user can select one of these three options.
And I need free search text field and submit button.

Views search would be fine, but I have with taxonomy filter. Here's example of my taxonomy tree:

Interests
- cooking
Skills
- woodcrafts
Professions
- programmer

Problem is that I need select list only to show those three main options, not sub-terms! That because when users are adding their professions, those are automatically added to taxonomy.

So is there module for this problem for views, cck or taxonomy. Or is there better way to handle this? I couldn't find custom search module or such..
