    OpenSearch

    OpenSearch

    Open source distributed and RESTful search engine

    OpenSearch is a distributed search and analytics engine based on Apache Lucene. After adding your data to OpenSearch, you can perform full-text searches on it with all of the features you might expect: search by field, search multiple indices, boost fields, rank results by score, sort results by field, and aggregate results. Unsurprisingly, people often use search engines like OpenSearch as the backend for a search application, think Wikipedia or an online store. It offers excellent performance and can scale up and down as the needs of the application grow or shrink. Its distributed design means that you interact with OpenSearch clusters. Each cluster is a collection of one or more nodes, servers that store your data and process search requests. You can run OpenSearch locally on a laptop, its system requirements are minimal, but you can also scale a single cluster to hundreds of powerful machines in a data center.

    Ransack

    Ransack

    Object-based searching

    Create search forms for your Ruby on Rails application with Ransack! Ransack is available in two modes: simple and advanced, allowing you to create either simple or advanced search forms. Simple mode works much like MetaSearch and is very easy to set up. The advanced mode makes use of Rails' nested attributes functionality in order to generate complex queries with nested AND/OR groupings, etc. This involves more complexity but does produce some very interesting search interfaces and puts more power in the hands of users. Ransack is compatible with Rails 5.0, 5.1, 5.2 and 6.0, and on Ruby 2.3 and later.
