In this article, we will explore the ins and outs of SQL Server Full Text Search to help you unlock its full potential. Let’s get started!

What is SQL Server Full Text Search?

SQL Server Full Text Search is a feature in Microsoft SQL Server that allows you to perform text-based searches on data in your database. With Full Text Search, you can quickly and easily search for keywords, phrases, and even complex queries within your data. This can be incredibly useful for a variety of applications and use cases, from e-commerce and content management systems to data analytics and business intelligence tools. Let’s take a closer look at how it works.

How Does SQL Server Full Text Search Work?

SQL Server Full Text Search works by creating an index of your database’s text-based data. This index contains all of the words and phrases in your data, along with information about where they appear and how they are related. When you perform a search using Full Text Search, the query is matched against this index to find the most relevant results. This process is incredibly fast and efficient, allowing you to search through large volumes of data in a matter of seconds.
