That link just proves that search results are no better than the entered search parameters.
I guess that you could address this issue by adding a new file to the SVN tree, make all the maps depend on that file and bump its revision whenever a change that requires maps to be rebuilt is made. However, that solution is messy and after all... we're talking development branch here.
On the other hand, easier update-build-run cycle will increase testing and draw focus to _real_ problems and improvement suggestions that we all will benefit from.
Cheers!
