Search or Module or Views

Hello !

I have a problem : I have a simple content type "document" (many fields : file, date, title,...)
I want to create a search engine only for this content type !

I don't know how i can manage with Views to manage undefined parameters ?

for example, these urls :

http://localhost/my_view/catid/1
http://localhost/my_view/catid/1/title/toto
http://localhost/my_view/title/toto
http://localhost/my_view/catid/1/title/toto/taxonomy/design

In these examples I have only one view and different parameters : in fact my users can or cannot have selected on or more parameters ?

But is it possible with one view ?

Thank you for your answers
