Add full text searching using Searchkick and Elasticsearch. Here I will show the steps involved in adding this search to an existing application and a sample of autocomplete functionality.

N+1 queries can make an application slow. Having queries called within views can also slow down an app as well as making it less extendable.

In this episode, we look at creating ruby objects. Then we look at different ways of implementing memoization and how it can be used to speed up our classes.

Adding indexes to your databases can increase the SQL search performance on your tables. As your application grows, migration files can become out of hand, use squasher to squish them down to a single file.
