Quick regex routing question

[eluser]darrenm[/eluser]
Hi there

I have controller that needs to take loads of arguments from a URL. The amount of arguments will vary.

As the URI is going to get pretty long I'm keen to lose the 'function' part of it and re-route along the lines of:

Code:

/productsearch/(varying*number*of*segments) = /productsearch/listingfunction/(*everything*)

Can anyone help me out with the regex specifics?

many thanks.
