Search function with multiple custom fields

I need a search function where I can filter by multiple custom fields.
Therefore I have created a menu item: Category list.
When calling this menu point now appear all the filters and - below - the list of category posts - unfiltered.
But I want: By the first call of the menu item, only the search filter shall be seen.
Is that possible with this menu item, or do I need a different method?
Thanks for your help.

Solved! I use the modul: "Content List Filter"
It works.
