Groups of exact words or phrases: Let's say we are looking for a content about yahoo messenger skins. Instead of type only yahoo messenger skins, in the Google search box, we will limit the results only to those that contain all three related words. To achieve this, we will put the words between quotation marks.
Example: “yahoo messenger skins”
Words excluded: Let's say we want to do a content search, after the words internet marketing, but sleep to exclude from the result of search, the term advertisement. To achieve this we must use the sign "-" in front of the word we want to exclude from results.
Example: "Internet marketing" - publicity
Pont: In the same way, the search results and the TLDs (the terminations of the domains. Eg: .ro, .com,, net, etc.) can be excluded. For example, if we sleep to seek internet marketing, but from the results displayed, the pages .ro, .com and .org, we use: we use: “internet marketing” –.ro –.com –.org
Search Terms, in a certain site: If a site does not have its own search system, we can use Google, to look for terms inside that site. This may be possible, if we use in search, the site address and key terms.
Example: “public hubs” site:stealthsettings.com
Types of specific documents: If you want to find results in files of a particular type, you can use the order “Filetype:”. For example, we want to seek, the words ”yahoo messenger"In PowerPoint (.PPT) presentations. To achieve this we use the following search expression:
Example: “yahoo messenger” filetype:.ppt
Alternative words and expressions: By default, when you do a search, Google will include all the conditions specified in search. If you are looking for the words "Internet marketing" but you want alternative results and "online advertising", to do this you can use the operator OR.
Example: "Internet marketing" or "online advertising"
*The operator "OR" must be written in capital letters (caps), to be understood by the search engine.
Searches in a certain time: This function, helps to find events and various things that have been part of a certain period of time. For example, we want data on seismic activity between 1900 and 2008. After the key word, we use as an operator for delimiting interval: 1900..2008.
Example: Seisms 1900..2008
After I thought about writing this post, I remembered that I still have something almost similar here: Google Search – Advanced Operators.
