Implementing Full-Text Search in Elixir Phoenix with Haystack

Source: culttt.com

Philip Brown outlines a step-by-step guide on adding full-text search capabilities to a Phoenix application using Haystack. The tutorial begins by setting up a basic Phoenix project without a database using the command 'mix phx.new'. He then proceeds to incorporate the NimblePublisher package for handling content-driven websites, creating structures for articles which include IDs, slugs, names, and bodies. After structuring articles and setting up NimblePublisher, Haystack is added to the project as a dependency for enabling full-text search. Brown details how to configure the Haystack search module, initialize structs, manage indexes, and leverage ETS for data storage. He introduces a search function within a 'search.ex' file to handle search requests. Finally, a live view module, 'SearchLive', is created to enable user interaction with the search feature within the Phoenix application. The app can then be tested to perform full-text searches on the provided content. The process shows the efficacy and simplicity of integrating Haystack for full-text search in Elixir applications.

Tutorial on Recognizing Handwritten Digits with Elixir ML

In this tutorial by Philip Brown, you will learn how to build an end-to-end machine learning project using Elixir. The tutorial covers everything from setting up the project using Phoenix, obtaining training data, preprocessing the data, building and training the model, and finally, creating a LiveView to accept user input and display predictions.
