A thing that recently strucked me about Google is the relevance of white-space between keywords. This is really relevant in queries. Although many people think that if you choose a name such as "foobar" Google will be able to make a distinction between the two, this is not the case when you enter "foo bar" in a search query. I've experienced this behavior myself by naming a directory "ie6fix". I expected to see a query like "ie6 fix" working well, but unfortunately it didn't work: Google indexed my document as "ie6fix", not as "ie6 fix".Try to run queries like "jquery ie6 fix" and "jquery ie6fix" and you will see it by yourself. Moral: white-space is relevant even when we choose a name to give to our documents.
