Here is a python-based search engine with an implementation inspired on one of our papers at the old Mi Islita.com site, now a search engine on Puerto Rico.
Great and positive accomplishment!
That tutorial is no longer at miislita.com, but was long ago moved to minerazzi.com. Find it here:
For other resources do a search for python in our IR miner at
For inquiries about that implementation, contact its author.
For other inquiries, applications, suggestions, drop me a line.
PS. Please note that Nullege.com itself is a search engine for finding python code. Here is a good example: http://nullege.com/codes/search/wx.calendar.CalendarCtrl
