En resumen:

1. A search is performed by a user

2. The WFE serving the call uses the associated search service application proxy to connect to a server running the Query and Site Settings Service also known as the Query Processor. It uses WCF for this communication.

3. The QP will connect to the following components to gather results merges\security trims and return results back to WFE:

Query Component - holds entire index or partition of an index

Property Store DB – holds metadata\properties of indexed content

Search Admin DB – holds Security Descriptors\Configuration data

4. WFE displays search results to the user
