P hrase your question in the form of an answer. So instead of typing, "What is the average rainfall in the Amazon basin?", you might get better results by typing "The average rainfall in the Amazon basin is."
§ T his is an old one, but very important: Put quotes around phrases that must be searched together. If you put quotes around "electric curtains," Google won't waste your time finding one set of Web pages containing the word "electric" and another set containing the word "curtains."
§ Similarly, put a hyphen right before any word you want screened out. If you're looking up dolphins, for example, you'll have to wade through a million Miami Dolphins pages unless you search for "dolphins - Miami."
§ Google is a global White Pages and Yellow Pages. Search for "phonebook:home depot norwalk , ct," Google instantly produces the address and phone number of the Norwalk Home Depot. This works with names ("phonebook:robert jones las vegas, NV") as well as businesses.
§ Don't put any space after "phonebook." And in all of the following examples, don't type the quotes I'm showing you here.
§ Google is a package tracker. Type a FedEx or UPS package number (just the digits); when you click Search, Google offers a link to its tracking information.
§ Google is a calculator. Type in an equation ("32+2345*3-234=").
§ Google is a units-of-measurement converter. Type "teaspoons in a gallon," for example, or "centimeters in a foot."
§ Google is a stock ticker. Type in AAPL or MSFT, for example, to see a link to the current Apple or Microsoft stock price, graphs, financial news and so on.
§ Google is an atlas. Type in an area code, like 212, to see a Mapquest map of the area.
§ Google is Wal-Mart's computer. Type in a UPC bar code number, such as "036000250015," to see the description of the product you've just "scanned in." (Thanks to the Google Blog,
http://google.blogspace.com , for this tip and the next couple.)
§ G oogle is an aviation buff. Type in a flight number like "United 22" for a link to a map of that flight's progress in the air. Or type in the tail number you see on an airplane for the full registration form for that plane.
§ Google is the Department of Motor Vehicles. Type in a VIN (vehicle identification number, which is etched onto a plate, usually on the door frame, of every car), like "JH4NA1157MT001832," to find out the car's year, make and model.

http://labs.google.com . Here, you'll find links to new, half-finished Google experiments-like Google Voice, in which you call (650) 623-6706, speak the words you want to search for and then open your browser to view the results. Disclaimer: It wasn't working when I tried it. (Ditto a lot of these experiments.)
........but have a WHOLE lot more to learn. There are those of you, here in the forum, who I think have acheived "guru" status with your computer skills. 
(maybe you haven't, but it seems that way to me)
I can read until I'm literally blue in the face and not come up with anything even remotely addressing Group 27 batteries. 
Needless to say, after an hour or so of reading, I give up. 
(far, far, far from reading all included in the 875 threads that supposedly matched my request) I know many people who can type something into a search box, hit the button, and find all the information they need. How do they do it? How would I find the information I'm seeking? 
Should I ask the search engine for something more or less specific?
I appreciate the help.
