LATEST UPDATE- It appears that the data for the bookmach site index was corrupted by my hosting provider when they were switching hard drives, and then they decided they weren’t going to support the version of PostgreSQL that it runs on. I have since switched providers and started repairing the database, but due to the age of the database version and the particular configurations it uses it is hard to find a managed server to host it. So for the time being it has been shut down, perhaps I can find time in the future to upgrade and revive it. Thanks to everyone who visited!
Apologies for the site problems last few weeks, the database became corrupted during a move. I’m replacing the text query engine, so bookmach should return stronger & faster than before. Watch this space for updates!
