How to Create a search function with nhibernate, linq?

I am going to build a search function today, c# asp.net. i need a push go get it rolling. i use nhibernate linq. it would be nice to do this with linq query. it need to be kinda dynamic, i am going to have several search criterias like gender, email, name, age and some more.

this search query is only going to my customer object.

how could i do this? and how is this done the right way?

the way i think now is that i get a iqueryable and perform queryies to that. i think like this that e.g for the gender i got two checkboxes, so i perform a if male is check i do a where.gender == "Male" and if none is checked i do nuthing. but is this the way to do this for every query? because some is user input to like name, email, age.

please advice me on this

You could analyze your search filter like this:

var query==...
if (filter.Name.Length>0)
   query=query.Where(name=...)
if (filter.Email.Length>0)
   query=query.Where(email=...)
