ransack VS pg_search

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

First of all, you should take a look at Active Admin's documentation regarding filters. You can continue your overview with the official README and wiki, where, among other things, you can find view-helpers to create custom search forms.

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).

The postfix _cont is one of the many predicates available in Ransack. Predicates determine which SQL query is to be generated for search. You can read more about all available predicates in the official wiki.

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

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.
