Home-Brewing a Full-Text Search in Google's AppEngine - I've recently deployed a django application on Google's AppEngine. I'm not sure how I've avoided it thus far but seems to fit my needs relatively well. DataStore (AppEngine's data storage engine) really impressed me. The python API feels so much like django's ORM that there was practically zero learning curve for a chap like me. One thing that disappointed me, however, was the state of the search facility. The built-in google.appengine.ext.search.SearchableModel suffers from many problems outlined all over the web. i.e. the need to create n indexes to handle for n search terms, index creation failures, inability to exclude properties and a lack of support for common search operations. A brief web search for alternatives turned up a semi-commercial product and a few open source offerings but nothing that really piqued...
