A Searchify PHP library is available to access the Searchify API. With the aim to simplify search-as-a-service, geolocation, and hosting, Searchify offers compatibility with IndexTank, useful to add custom-made real-time full text search to a website or an app. Authored on GitHub by developer Adrián.
The Tapir API is really 3: Search, Ping and Post to give you the power to make your blog searchable, get your articles indexed immediately, and push content manually. Indexing of the Rss feed is done at 15 minute intervals. According to the API documentation, the results are returned in JSON or JSONP.
Yesterday's Mashup of the Day was a fun one for those who miss the good old days of command shells, goosh.org, "the unofficial google shell". Developer Stefan Grothkopp coded this on top of the Google Ajax Search API to give you a command shell for interacting with Google search queries.
