These changes are some of the largest changes since the search algorithm has been designed over 10 years ago and impact one of the more complex parts of the server.
I am appalled at this not being documented when the changes were made. I personally took a lot of effort in making sure the documentation was pretty, informative and allowed new comers and those new to this region of the code to understand how it worked. Those who made these changes benefited from my thorough documentation. They need to carry on the tradition and make sure others after them also benefit, and don't detriment from it by documenting their changes.
Why is it that others do not feel this way? I can understand straight forward areas that document themselves well in code alone but people need to consider new comers that want to get into the more complex code. They should update these parts of the documentation even if it's not pretty documentation.
Also it's no excuse to say we need the 2.0 to stabilize otherwise the docs will change. Over the past ten years very little has changed in our search algorithm. So this is not a region of code that we f**k with often since it's so critical to the servers operation.
Committers making changes to "complex" regions of code should think about others that come after them to maintain their code. This is just good community citizenship. Those that don't really don't care about the community. Being polite is not just about correct speech with words like sir and madam. It's ones actions considering others.
Sorry Emmanuel this was a bit off topic but it's something we all need to consider. I will try to respond to your comments later. I'm not immediately available these days but I will not forget to answer these emails even if it takes me some time.
