Google Keyword Tool: Results Incomplete

Why don't they give us the full results?

[LukeC]

Has anyone else noticed how the Google Keyword Tool doesn't give you all the results?

When I search on widgets it misses out some of the brands in this area, but not all over them. I know it's doing this as I can see from my adwords campaigns that "brandname widget" sometimes gets as much traffic as just "widget".

Why do Google do this, it must be deliberate.

Given that we are allowed to bid on these brand names, I do not understand why they would choose to hide them from the results.

Does anyone else find this with their vertical?

This is a bit like site: search results. The only way to get a complete list is to recursively lookup keywords - a pain, and I agree there should be a way to do this without having to use multiple queries.

I don't think it's a case of "hiding" them, but as with web search, Google deciding what you really "meant" to look for, and not bothering to even query the rest ;)
