A good pattern for complex search criteria?

[21thermostat]

I am currently working on a store search function. The search criteria are quite complex, for example:

Footage >= 50 AND (SizeCode == SizeType.Large OR MobileEnd == "ABC") 

I think that each criterion could be represented by a Func<store, boot> (I am using C# and LINQ).

Func<Store, bool> filter1 = (s => s.Footage >= 50);
Func<Store, bool> filter2 = (s => s.MobileEnd =="abc");
Func<Store, bool> filter3 = (s => s.SizeCode == SizeType.Large);

My question is how I can deal with AND, OR, NOT logic, and order of precedence. How can I convert the user input into a LINQ expression?

Thanks.

Of course. We know every criteria are important and very critical of what we do. If you have great criteria to use it, make sure that you have a successful future to come.
