Hack 5. Check Your Spelling
Google sometimes takes the liberty of "correcting" what it perceives is a spelling error in your query.
If you've ever used other Internet search engines, you'll have experienced what I call stupid spellcheck. That's when you enter a proper noun and the search engine suggests a completely ludicrous query ("Elvish Parsley" for "Elvis Presley"). Google's quite a bit smarter than that.
When Google thinks it can spell individual words or complete phrases in your search query better than you can, it'll suggest a "better" search, hyperlinking it directly to a query. For example, if you search for hydrecefallus, Google will ask if you meant hydrocephalus, as shown in Figure 1-16.
Figure 1-16. Google offers spelling suggestions when it thinks it knows better
Suggestions aside, Google will assume that you know of what you speak and return your requested results, provided that your query gleaned results.
If your query found no results for the spellings you provided and Google believes it knows better, it will automatically run a new search of its own suggestions. Thus, a search for hydrecefallus finding (hopefully) no results will spark a Google-initiated search for hydrocephalus.
Mind you, Google does not arbitrarily come up with its suggestions, but builds them based on its own database of words and phrases found while indexing the Web. If you search for nonsense like garafghafdghasdg, you'll get no results and be offered no suggestions.
1.17.1. Embrace Misspellings
Don't make the mistake of automatically dismissing the proffered results from a misspelled word, particularly a proper name. I've been a fan of cartoonist Bill Mauldin for years now, but I repeatedly misspell his name as "Bill Maudlin." And judging from a quick Google search, I'm not the only one. There is no law stating that every page must be spellchecked before it goes online, so it's often worth taking a look at results despite misspellings.
As an experiment, try searching for two misspelled words on a related topic, like ventriculostomy hydrocephalis. What kind of information did you get? Could the information you got, if any, be grouped into a particular online genre?
At the time of this writing, the search for ventriculostomy hydrocephalis gets only 10 results. The content here is generally from people dealing with various neurosurgical problems. Again, there is no law that states that all web materials have to be spellchecked.
Use this to your advantage as a researcher. When you're looking for layman accounts of illness and injury, the content you desire might actually be more often misspelled than not. On the other hand, when looking for highly technical information or references from credible sources, filtering out misspelled queries will bring you closer to the information you seek.
