Enjoyed this. I look forward to seeing more people/companies take on building their own indexes from scratch. It's not only fun (to some extent) but can be very valuable given the right use case. We've built a search engine at my company over the past year that now gives us significant business value and competitive advantage, has an index of fewer than 1 million records, is currently for internal use only, and listings only live for 30 days after inclusion. Would that work for a general purpose search engine? No. But for very domain specific, tight use cases, even a small index could make a difference to business processes.
