We all are used to search google blatantly and i must say rather naively.
Google can be used much more efficiently with many times more productivity. Here are methods one can bring into play to search more effectively(pretty easy methods and possibly many of them you may be knowing )
For searches containing multiple keywords, not all words come up in the search result. This can be attributed to Google’s way of giving you the most relevant results. To force a certain keyword or phrase to be included in the search,
Try to use “+”(plus) sign in front of the word and Google will make sure that the word is definitely included in the results.
If you want pages to appear in search result which contain at least one keyword then use the OR operator or use the “|” symbol (pipe symbol) to save you a keystroke. “smart | bald | man”
If you want to search for an exact phrase, use quotes. [“smart bald man”] will only find that exact phrase. [smart “bald man”] will find pages that contain the word smart and the exact phrase “bald man”.
use the “-” symbol, if you don’t want a term or phrase. [-smart bald man] will return pages that contain “bald” and “man” but that don’t contain “smart”.
Similar terms (Synonym Search).
Use the “~” symbol to return similar terms. [~smart little man -smart] will get you pages that contain “ dumb little man” and “stupid little man” but not “smart little man”.
The “*” symbol is a wildcard. This is useful if you’re trying to find the lyrics to a song, but can’t remember the exact lyrics. [I have * numb lyrics] will return the Pink Foyd song you’re looking for.
For searching specific file type use “?intitle:index.of?filetype search string” before you search query. For Example “?intitle:index.of?pdf brave new world” will fetch you all PDFs related with Brave New World novel. You can use this for any file types including ppt,doc,xls,mp3,avi or anything you want.
If you can’t remember any of these operators, you can always use Google’s advanced search. Google has an excellent advanced search facility to help refine your searching. Rather than replicate this here, a PDF document can be downloaded here. Click on Advanced Search Tips in advanced Search Screen for more tips.
Cached pages (Find lost pages).
For pages that take too long to open due to some problem, pages which have been deleted or forums which require password use Google cache. At the bottom of each result there is a link for opening cached pages (most of the times). But not all forums and pages are there in Google cache and also Google cache is also old version of the webpage you are trying to access.
This little-known feature searches for a range of numbers. For example, [“best books 2000..2009”] will return lists of best books for each of the years from 2000 to 2009 (note the two periods between the two numbers).
Use the “define:” operator to get a quick definition. [define:sequitur] will give you a whole host of definitions from different sources, with links.
Searching by URLs
You can also search for terms that occur in the URLs of documents. For example, if you want to find the word “mac” in the sites that have “apple” in the URL, where “mac” may or may not be in the URL, use this “inurl:applemac”…the word apple will then be in the URL. Note that there should be no space between “inurl” and “apple”.
P.S : Despite all this you still have to use your head to search more efficiently. Don’t just type in the whole sentence ever.
