First result with the mixed-index branch, processing Spain with default 
style
Total time taken: 391216ms vs 449649ms with r2661
index size: 29 MB vs 21.6 MB with r2661
Apart from the numbers, the address search doesn't work by now. Entries 
in the index are not unique and are not ordered (see screenshot 1). When 
you type a letter search results don't change accordingly (screenshot 
2). This is the console output, if it is of any help:
