  • Open iOS source search framework
    My open source iOS and OS X search framework, SearchTouch, is available on Github. Written in pure Objective C, it will enable you to implement fast search of your data on iOS devices and Macs. The code is modular to allow different storage back ends. The main back end uses Core Data.

Introduction

My name is Julian Richardson. I am a software engineer at Google, working on the Google+ iOS app.

I realized when the iPhone came out that mobile was going to be a huge paradigm shift. A little after that, I started working full time on iOS development. In addition to Objective C and iOS development, I have extensive experience in web scale search, team leadership, natural language processing, and AI, amongst other areas.

I am currently very interested in machine learning and Clojure.

In my spare time I build things using Arduino and AVR processors, cut things up using a laser, and design and print objects on my home-built Reprap Prusa 3D printer.

I am working on porting parts of my old blog into the new site. Until that is done, I will continue to post to the old blog. You can read my posts on my Mindmash blog (click through for startling design change!).

SearchTouch – Open Source Search

SearchTouch is an open search framework for iOS and Mac which provides fast on-device search.

Books and other medium-sized document sets easily fit on iOS devices. Using SearchTouch, your app can avoid the dependence on a server for search facilities. Search remains available offline, and can be much more responsive than server-side search. You can download the code from https://github.com/spoogle/SearchTouch.

SearchTouch has been developed by Julian Richardson. Contributions are very welcome. Please contact me by email at julianrichardson@acm.org if you would like to contribute, or if you have bug reports, questions or suggestions.
