best design pattern for quick search in client server environment

We are looking to develop a quick search similar to google finance (when start typing the stock it start showing the matched ones in dropdown). We have around 200K records in oracle DB & based on the search we might end up with 50k to 60k records. Since it is lot of data we cannot bring everything to client machine. what is the design design pattern used in these scenarios.

Our technology stack

DB: Oracle

service layer : some Java web services, some in .NET WCF services. Mainly Java

UI - WPF & AngularJS (We have windows & web client)

thanks in advance
