Basic Search Technique 

Everyone who want to find information in the internet want the best answer for their inquires. But not most of the internet user know how to get specific information they wished for. Here I wrote steps how internet user can get the precise answer from their inquires :)

1. Identify your concepts
When planning your search, break down your topic into its separate concepts. Let's say you're interested in the effects of global warming on crops. In this case, you have two concepts: GLOBAL WARMING and CROPS.

2. Make a list of search terms for each concept
Once you have identified your concepts, list the terms which describe each concept. Some concepts may have only one term, while others may have many.
global warming
greenhouse effect
greenhouse gases
climate change
crops
crop yields
crop production
food supply
These lists are a suggestion. Depending on the focus of your search, there may be other terms more suited to what you're looking for.

3. Phrase Search and Exact Word Search

Some words naturally appear in the context of a phrase, for example, freedom of the press. To search on phrases in most search engines, simply enclose the phrase within quotes: "freedom of the press".
Phrases are especially important when there are STOP WORDS in your search. These are "little" words such as a, and, the, in, it, etc. Most search engines tend to ignore these words. If you want to be sure they are included in your search results, enclose them with the rest of your search within quotes.
In fact, whenever you want to search any word exactly as you have typed it, enclose the word within quotes:"president". In many search engines, this will ensure that only this exact word will be searched. The search engine will not look for any variations, such as presidents, presidential, etc.

4.Field Search

Field searching is an optional way to focus your search results. With general search engines, you're searching the full text of many millions of pages, and field searching can help you retrieve results that may be more manageable. For example, you can search for words that appear within a particular Web site, within the URL (Web address), in the page title, and so on. The exact technique for doing this can differ among search engines, so be sure to check out the Help pages before proceeding. Let's consider a couple of examples on Google.
A title search can bring you more relevant results than merely searching for words that appear anywhere on the Web page. It's more likely that a document that contains your search words in the title will be more relevant that a document that does not. For this reason, many search engines use title words as an important way of ranking search results in order of their relevancy.
5.Title Field 
Let's look for Web pages that contain our search terms in the page title. Again, we'll use Google to try this out, revisiting its advanced search page. Here, you need to open up the page to display all its options by clicking on the plus sign (+) near the bottom of the page next to the options for Date, usage rights, numeric range, and more.

Where your keywords show up gives you the option to select in the title of the page. Let's search forhurricane caribbean deaths.
Notice that Google translated this search into allintitle: hurricane caribbean deaths. If you memorize this search syntax, you can conduct this search from Google's main search page.
6. Site field
Searching on the site field is another useful way of finding relevant results. In this case, you search on the top-level and second-level domain names together, and then use AND logic to add topical words to your search.
You can read about domain structures in the tutorial A Basic Guide to the World Wide Web. Briefly, to take an example shown below: "nasa" is a second-level domain, and "gov" is a top-level domain.
Examples of sites:
nasa.gov
mit.edu
microsoft.com
Let's look at an example of a site search. Let's say you are searching for information about spacewalks conducted by NASA. Try this: spacewalks site:nasa.gov. This search will limit your results to pages on the NASA Web site.
Notice that all the results come from the site nasa.gov. You can also go to the advanced search page on Google to conduct this search.
