Until I saw the reply from Jim TxMiller, I thought your question was about how does one search for your hubs in Google search results, and that's still the way I'm going to view the question.
To find your hubs in Google search results, you would take the title of your hub, or a short phrase from your hub and type that or copy paste it into the Google search bar, and then click the blue search button.
You would then scroll down through the ten search results on that page, and see if a title, description, and link to your hub is there. If not, you'd go to page 2, and so on and so on.
The reason why I say you'd type the title of your hub or a phrase from your hub into the Google search bar is because that's how natural search results work. If people use Google to search for information about something, Google tries to match up the words in their search phrase with words that are on a website page - this is why it is important to use words in your hubs that people do at least sometimes use when they look for information on the Internet. (If ypu are trying to get your hub found by people in search results when they use the Internet to look for information about something.
To know if people use the words or phrases in your hubs, use the free Google Adwords Keyword Tool to check. You type a phrase into the Google Adwords Keyword Tool, and then in the list of results you can see how many searches were done, on average, per month, over the past 12 months (search volume.)
If you scroll past many pages of search results before you find a title, description and link to your hub, it means many other website pages with the same or similar phrase in them are beating you in the search results postions.
Also, having a Google page one result for any particular search phrase doesn't necessarily mean your hub will get traffic - it will get traffic only if the search phrase you have used has search volume (if other people other than you use that phrase to look for information on the Internet.)
