Here are some quick tips to get you started
Enter your search terms in lower case.
The search engine will find both upper and lower case instances of your search term.
Enclose terms in double quotation marks if you want the search engine to take them literally.
Search for phrases by entering the words separated by spaces.
The search engine will find pages that contain all of your search terms.
The search engine ignores common words such as "where" and "how", because they tend to slow down your search without improving the results. If a common word is essential to getting the results you want, do a phrase search, which simply means putting quotation marks around two or more words. Common words in a phrase search (e.g., "where are you") are included in the search.
