Google has done a terrific job in search industry by introducing their search engine years ago.
Today, It is no doubt the most powerful search engine.
Google Simple Search
We can simply search Google by writing the words we want to know about and that's it. We eventually find something useful.
Have you ever noticed the amount of time you waste by doing this?
Advanced Google Search - Ethical Google Hacking
We need to be a little more sophisticated while search through Google. Using operators is the best way for getting quality results.
Google Operators:Operators are used to enhance results and to maximize the search value. These are our tools as well as deadly hackers’ weapons.
Basic Operators: +, -, ~ , ., *, “”, |, OR
Advanced Operators:allintext:, allintitle:, allinurl:, bphonebook:, cache:, define:, filetype:, info:, intext:, intitle:, inurl:, link:, phonebook:, related:, rphonebook:, site:, numrange:, daterange
Basic Operators
(+) force inclusion of something common
Google ignores common words (where, how, digit, single letters) by default:
Example: StarStar Wars Episode +I
(-) exclude a search term
Example: apple –red
(“) use quotes around a search term to search exact phrases:
Example: “Robert Masse”
Robert masse without “” has the 309,000 results, but “robert masse” only has 927 results. Reduce the 99% irrelevant results
(~) search synonym:
Example: ~food
Return the results about food as well as recipe, nutrition and cooking information
( . ) a single-character wildcard:
Example: m.trix
Return the results of M@trix, matrix, metrix…….
( * ) any word wildcard
Advanced Operators:
“Site:”
Site: Domain_name
Find Web pages only on the specified domain. If we search a specific site, usually we get the Web structure of the domain
