The power of Azure Search comes when you need to perform a full-text search to find relevant documents that will satisfy your query. This Azure service uses Apache Lucene under the hood, which is a well-known, high-performance search engine written in Java.
You can find more information about Lucene here: https://lucene.apache.org/core/. It is an open source project available to download for everyone.
In this chapter, you will learn how to perform a full-text search, what is the syntax, and how to recognize potential issues.
