Search operators are methods to help you quickly search and find subjects and types of information of interest.
1. PDF Operator and other Filetype Operators: To find all PDFs on a given subject, including PDF books, or to search for a book or article that may be PDFed, use thee following operator
"Subject or title of interest" put any other words here then filetype:pdf or any other file type; Some common file types are: .ppt, .pptx,
2. Site Operator: This will allow you to find any person term, word on a given website, among its hundreds of files, subfile, etc. example shown for Reocities.com
site:reocities.com then at least one space, and then the term, word,etc, which may be in quotes; The only part of the URL is the part after the //, and then the .com, .org, etc.; Apparently the terms can also go before the site operator;
3. Links To Operator: Identifies all websites that have a link from their website to the website you are interested in: For example, to find who is linking to Wisewiki.org, put "linkto:wisewiki.org" in the Google search box. But to get only the links that are outside the website of interest, you have to put in "-wisewiki.org"; So the search will be:
linkto:wisewiki.org -wisewiki.org
An Alternative "links to" is the operator: links:(URL of home website)
4. Links From Operator: This is a search operator that finds all the links from a given domain name. It is not available by Google, but only by Bing.com
LinkFromDomain:wisewiki.org , which give over 65,000 links;
5. In URL Operator: To find a URL that has a particlular word or set of letters or numbers, such as pdf, doc, docx, archive, volume, etc: Example: www.cleartechelectronics.com inurl:pdf gives all the PDFs that are available in that domain name; So you could go to Pleyedes and others and ID all the PDFs; And this works, even if the website itself is "forbidden", because Google searches the URLs; Also, The extreme searcher gave this as an example:
members inurl:aiip , which would search for all URLs with aiip in it and the word members;
6. Boolean Operators: These vary by search engine: Google uses AND, OR, and the negative sign (-); eg A AND B OR C -D; Yahoo and Bing: A (B OR C) -D or NOT D;
Search order of Boolean Operators:
Databases follow commands you type in and return results based on those commands. Be aware of the logical order in which words are connected when using Boolean operators: Databases usually recognize AND as the primary operator, and will connect concepts with AND together first.
If you use a combination of AND and OR operators in a search, enclose the words to be "ORed" together in parentheses. Examples: ethics AND (cloning OR reproductive techniques)
(ethic* OR moral*) AND (bioengineering OR cloning)
