intitle:

The “intitle:” syntax helps Google restrict the search results to pages containing that word in the title.
For example, “intitle: w1 w2” (without quotes) will return links to those pages that has the word "w1" in their title, and the word "w2" anywhere in the page.
Similarly, if one has to query for more than one word in the page title then in that case “allintitle:” can be used instead of “intitle” to get the list of pages containing all those words in its title.
For example using “intitle: w1 intitle: w2” is same as querying “allintitle: w1 w2”.

inurl:

The “inurl:” syntax restricts the search results to those URLs containing the search keyword.
For example: “inurl: w” (without quotes) will return only links to those pages that have "w" in the URL.
Similarly, if one has to query for more than one word in an URL then in that case “allinurl:” can be used instead of “inurl” to get the list of URLs containing all those search keywords in it.
For example: “allinurl: w1/w2“ will look for the URLs containing “w1” and “w2”. The slash (“/”) between the words will be ignored by Google.

site:

The “site:” syntax restricts Google to query for certain keywords in a particular site or domain.
For example: “w1 site:google.com” (without quotes) will look for the keyword “w2” in those pages present in all the links of the domain “google.com”. There should not be any space between
“site:” and the “domain name”.

filetype:

This “filetype:” syntax restricts Google search for files on internet with particular extensions (i.e. doc, pdf, bin,... ).
For example: “filetype:doc site:com w” (without quotes) will look for files with “.doc” extension in all domains with “.com” extension and containing the word “w” either in the pages or in the “.doc” file.

link:

“link:” syntax will list down webpages that have links to the specified webpage.
For example: “link:www.google.com” will list webpages that have links pointing to the google homepage.
Note there can be no space between the "link:" and the web page url.

related:

The “related:” will list web pages that are "similar" to a specified web page.
For example: “related:www.google.com” will list web pages that are similar to the google homepage.
Note there can be no space between the "related:" and the web page url.

cache:

The query “cache:” will show the version of the web page that Google has in its cache.
For example: “cache:www.google.com” will show Google' cache of the Google homepage. Note there can be no space between the "cache:" and the web page url.
If you include other words in the query, Google will highlight those words within the cached document.
For example: “cache:www.google.com w” will show the cached content with the word "w" highlighted.

intext:

The “intext:” syntax searches for words in a particular website. It ignores links or URLs and page titles.
For example: “intext:w” (without quotes) will return only links to those web pages that has the search keyword "w" in its webpage.
