Think of a search engine's web host as being streamlined. This system has 100 machines that can reply to search queries. These machines can then call out to another cluster of machines using the processSearch(string query) function to actually obtain the results. You cannot ensure that the same machine will always reply to the same query because the machine that answers a given query is selected at random. ProcessSearch is a very pricy technique. Create a caching system to store the outcomes of recent searches. Don't forget to describe how you'd refresh the cache if the data changed.

Concurrency Control

The simultaneous occurrence of two or more operations is called concurrence and the situation is called concurrency. In concurrency, the function of one operation can affect the function of the other and put data integrity at risk. Hence, management for the control of concurrency is required. The management or controlling system in the Database Management System (DBMS) that coordinates concurrent access is called the concurrency control system.
