Basic full-text search
Searching text will become something you do repeatedly when building applications or exploring data sets for data science. Full-text search is helpful when performing exploratory data analysis for a natural language processing model or building a search feature into your application.
In this exercise, you will practice searching a text column and match it against a string. The search will return the same result as a query that uses the LIKE operator with the % wildcard at the beginning and end of the string, but will perform much better and provide you with a foundation for more advanced full-text search queries. Let's dive in.
