Moust of all :)
Tip 3: Choose words carefully
When you're deciding what words to put in the search box, try to choose words that are likely to appear on the site you're looking for. For example, instead of saying my head hurts, say headache, because that’s the word a medical site would use.

My advice to google is: why carefully? Are you so slow for search in context?
Any way. If you are start to be obsed with same result use this tip. ;)
