DEPRECATED: Google has announced the Custom Search JSON API will be shut down on January 1, 2027. This gem will raise a DeprecatedError on instantiation. Please migrate to one of these alternatives before the shutdown date: - Algolia (https://www.algolia.com/) — hosted search with a generous free tier - Meilisearch (https://www.meilisearch.com/) — fast, open-source, self-hostable - Typesense (https://typesense.org/) — open-source, typo-tolerant search Original purpose: Ruby interface for the Google Custom Search JSON API, allowing Rails applications to add Google-powered site search using a Custom Search Engine ID.
