Is there a way to implement Azure Search with Sitecore 8.1x? Currently I can see only one option to update current Sitecore instance to 8.2x.
Jamie Scott has implemented Azure Search for Sitecore 8.1. However this is not officially supported by Sitecore. Here is the git repo for the same. https://github.com/jscott1277/SitecoreAzureSearchProvider
