ransack VS pg_search

You might be looking for something like Ransack - https://github.com/activerecord-hackery/ransack

I use ransack for this and find it very powerful and flexible without the need to rely on complex JS.

For especially complicated cases, you can consider learning how to create custom predicates and Ransackers - extensions that convert parameters directly into Arel (internal library ActiveRecord, used to build SQL queries).

You can use gems like Ransack to build search forms much faster, but for the purpose of learning and performance we will be building this feature ourselves. Throughout the process, you will also learn how to customize Rails default pluralization. By the end, we will be able to search for Pokemon by name, type, and region.

Facets are possible in Postgres but it looks complex:

pg_search [0] not to be confused with the ruby gem of the same name [1]:

On the backend, we'll need a few tools. Apart from the classics (ActiveRecord scopes and the pg_search gem), you’ll see how the (yet officially unreleased but production-tested) all_futures gem, built by SR authors, will act as an ideal ephemeral object to temporarily store our filter params and host our search logic. Finally, we’ll use pagy for pagination duties.

You can take a look at pg_search if you’re using Postgres

This was a really good read, thanks. I've got into the habit of jumping straight to PgSearch but could definitely apply this approach to some existing projects.

Cleaner, more performant database queries: Definitely don't just leave your query sitting in the controller! For production use cases, you'd want to consider an option like pg_search

If you are using Rails with Postgres you can use pg_search gem to build the named scopes to take advantage of full text search.

Hey guys. Looking to release an app for mobile that will be using a rails API. The app will heavily rely on search. I know the go-to is to use elasticsearch but wanted to see if there was enough user demand for the MVP before shelling out $50/mo for the heroku add on. In the mean time I've been using pg_search. From the eye test it's performing okay but will be adding a table that houses over 350K records. With this in mind I was wondering if you all had any tips for increasing the overall speed for search from the model and controller level. Also should note that I'm open to any other free search gems if they deem bette fit.

There are two basic search configurations with pg_search, a Single Model search scope or a multi Model configuration. In my case I am only using the Single Model configuration, but you can read more about multi-search in the documentation.
