Putting it all together

In this exercise, we are going to use many of the techniques and concepts we learned throughout the course to generate a data set that we could use to predict whether the words and phrases used to describe a film have an impact on the number of rentals.

First, you need to create a tsvector from the description column in the film table. You will match against a tsquery to determine if the phrase "Astounding Drama" leads to more rentals per month. Next, create a new column using the similarity function to rank the film descriptions based on this phrase.

Select the title and description for all DVDs from the film table.
Perform a full-text search by converting the description to a tsvector and match it to the phrase 'Astounding & Drama' using a tsquery in the WHERE clause.
