Power searching with google

Power Searching with Google


Made by : Nouri Hamza

CLASS I / Introduction

Filter image results by color :

How search works :
* When you're searching in Google, you're searching google's index of the web(with spiders)
* Page Rank Formula :
   A webpage's rank is determined by how many outside links points to it, and how improtant those links    
* Ads : the top and the right 

The art of keyword choices :

1. think about what you're trying to find

2. choose words that you think will appear on the page

3. put yourself in the mindset pf the author of those words

Keep the keyword on topic, try to keep the words that you expect to find on exactly the perfect results page.

Word Order matters :

* Different results(who, a who, the who)
                          (sky blue, blue sky)
                         (black and white, white and black)
* Every word matters in the query, even the word order can make a difference
* Captalization don't matter (and special characters)
* + in front of a name or a company will give you the G+ version of tha result
Punctuation that matters, when connected to a search term with no spaces in between: @, #, ++, +, %, $ (e.g., @researchwell, 43%, or c++)
Punctuation that Google ignores: ¶, £, €, ©, ®, ÷, §, (), ?, !

Finding text on a web page
* Use the CTRL+F to locate a word on a web page
Please note that at this time, there is no easy way to use Control-F/ Command-F to find two words near each other if they are not adjacent.  

Class 2 : Interpreting results

When search results suggest something new :
* Panels on the right-hand side :
  Google often provides a panel on the right-hand side that contains a summary of information it 
  knows about the entity that you're searching for.

Autocomplete :
   when you type in queries, Google provides suggestions immediately below the query box.

Search-as-you-type :
  As you type a query, you may notice Google offering results that change with each new letter 
  you type in.

Related searches :
   Scroll down to the bottom of the first page of results, and you can see a bunch of related  
  queries at the bottom of the page.

Thinking more deeply about your search :
When you see a new word, it is always a good idea to confirm what it means. An easy way to do this with Google is to ask for a dictionary definition by using the query: define "word"

Understand options for different media :

Reading the Search Engine Results Page (SERP)

Note that in the abstract,the ellipsis (...) indicate that you are seeing phrases from two different parts of the webpage. The information in between may change the meaning of what you see in the snippet.

Different kinds of content

Class 3 : Advanced techniques

Operator : Site
you can use the operator "site" to restrict results to either a specific top-level domain or a specific website.
Searching the keyword "simpson" in .gov websites

Searching the keyword"simpson" in the website

Searchin images with the keyword "simpson" in the website

operator : filetype
 is the way of limiting your results to files and documents of a particular kind.
Note that there are lots of different kinds of documents out there, including PDF files, flash files (SWF), Google Earth files (KML), Excel files (XLS), Comma-separated values (CSV) and more. 
You can combine the site operator and the filetype operator.
There should not be a space between filetype, the colon, and the extension: [filetype:txt]

Searching for all pdf files with the keyword homer
Searching all the pdf files with the keyword pdf in all the websites with the domain .com

Removing invasive results
When you put a minus sign in front of a term, it's as though you're erasing all results the that include that term.
There must be a space before the minus sign.
There must not be a space between the minus sign and the word you want to eliminate.

Notice the difference of results between these two cases:
Searchin the key word simpson

Searching the keyword simpson without the word homer

Double quotes are used to keep words together in a search.
The goal is to focus the results on pages where those words appear in the phrase. 

It provides a way of combining ideas so that you can search for pages including at least one out of a set of related terms or synonyms.
If an idea on one side of the OR is more than one word, it needs quotes around it

intext operator
 It allows you to find pages that have a specific word in the body of the text somewhere--it forces inclusion on the page.

Advanced Search
Access the Advanced Search form by clicking on the gear icon in the upper right-hand corner of the page.

The Advanced Search form guides you through building more complex searches, even when you cannot remember all the operators. It also offers extra options, such a specifying a region or language to search, or finding content that is pre-approved for reuse.
