Here's something I just noticed. Non-English Google sites (such as google.com.hk, google.co.jp, google.hr, google.de, etc) used to index much fewer pages for large English-language sites than google.com, google.co.uk, google.in etc. For example, an English-language site might have had 500,000 pages indexed in google.com (and google.co.uk etc) but only 170,000 indexed in google.co.jp. That discrepancy is GONE. The number of pages indexed is pretty much the same across all Google interfaces. This happened within the past month or so. It could be that they are just consolidating information across data centers but recall that the discrepancy wasn't geographic - it was linguistic. So what this indicates to me is that whereas previously Google had to compromise and index based on priority, the constraints on storage are no longer an issue. Did Google just add 500,000 servers? That might imply that henceforth Google will index your unindexed pages more readily. It's a bit of a stretch, but let's hope that's the case.
it could be true as other people from different country may not understand english at all. although i disagree with localisation but for this i agree
