Fast autofill from in-memory collection (.NET)

Question

I have this text input field on a web page. The types of users in the names of the products to purchase. I would like to provide a drop-down menu with possible names based on the letters entered so far.

The question is how to implement a server search (ASP.NET MVC). I will probably load a whole collection of element names (there are more than 100,000) in a static variable when the application starts. How to implement an efficient search for names starting with a given one or more characters?

TIA
