USING THE INTERNET
   ASSIGNMENT B1: USING THE INTERNET
 1. First write a few paragraphs introducing the task you are going to undertake.
 Use these Headings:
         • Chosen Topic - Identify your topic - this must be from a subject you are studying. Explain
         exactly what information you will need to find regarding this topic
              • Search Engines to be used - list three search engines you intend to use. Screen dump the logo of each.
              Indicate if you used a *metasearch engine.


  2. Next browse and search the internet using your chosen search engines. Make good use of
  Boolean statements.

  Produce the following evidence:
          • Search Refinements - take each search engine and show:
                • a screen dump with the number of results before refining (3 screen dumps)
                • a screen dump with the number of results after refining (3 screen dumps)
                       there must be a significant drop in the number of results

               • Search Results - take each search engine in turn and list some of the sites which you
               discovered

               • Chosen Sites - list 3 sites which you intend to use for your research. For each chosen site
               explain how you arrived at it. ie how you refined your searches to find it. Include the
               number of pages you found when you searched to emphasise the value of refining searches.
               Briefly explain what type of information you hope to gain from the site.



*A meta-search engine is a search engine that sends user requests to several other search engines and/or databases and returns the results from
each one

USING THE INTERNET
  Using Boolean Searches

 Search engines are very different from subject directories. While humans organize and catalog subject directories, search engines rely
 on computer programs called spiders or robots to crawl the Web and log the words on each page. With a search engine, keywords
 related to a topic are typed into a search "box." The search engine scans its database and returns a file with links to websites containing
 the word or words specified. Because these databases are very large, search engines often return thousands of results. Without search
 strategies or techniques, finding what you need can be like finding a needle in a haystack.

 To use search engines effectively, it is essential to apply techniques that narrow results and push the most relevant pages to the top of
 the results list. Below are a number of strategies for boosting search engine performance.

 IDENTIFY KEYWORDS

 When conducting a search, break down the topic into key concepts. For example, to find information on what the FCC has said about the
 wireless communications industry, the keywords might be:

 FCC wireless communication




BOOLEAN AND

Connecting search terms with AND tells the search engine to retrieve web pages containing ALL the keywords.

FCC and wireless and communication

The search engine will not return pages with just the word FCC. Neither will it return pages with the word FCC and the word wireless.
The search engine will only return pages where the words FCC, wireless, and communication all appear somewhere on the page. Thus,
AND helps to narrow your search results as it limits results to pages where all the keywords appear.




GCSE ICT (CCEA) - Assignment B1 Guide




USING THE INTERNET
  Using Boolean Searches

 BOOLEAN OR

 Linking search terms with OR tells the search engine to retrieve web pages containing ANY and ALL keywords.

 (FCC or wireless or communication)

 When OR is used, the search engine returns pages with a single keyword, several keywords, and all keywords. Thus, OR expands
 your search results. Use OR when you have common synonyms for a keyword. Surround OR statements with parentheses for best
 results. To narrow results as much as possible, combine OR statements with AND statements.

 For example, the following search statement locates information on purchasing a used car:

 (car or automobile or vehicle) and (buy or purchase) and used




 BOOLEAN AND NOT

 AND NOT tells the search engine to retrieve web pages containing one keyword but not the other.

 dolphins and not Miami

 The above example instructs the search engine to return web pages about dolphins but not web pages about the "Miami Dolphins"
 football team. Use AND NOT when you have a keyword that has multiple meanings. The need for AND NOT often becomes apparent
 after you perform an initial search. If your search results contain irrelevant results (e.g., Saturn the car rather than Saturn the planet),
 consider using AND NOT to filter out the undesired websites.




GCSE ICT (CCEA) - Assignment B1 Guide
USING THE INTERNET
  Using Boolean Searches
 IMPLIED BOOLEAN: PLUS & MINUS

 In many search engines, the plus and minus symbols can be used as alternatives to full Boolean AND and AND NOT. The plus sign
 (+) is the equivalent of AND, and the minus sign (-) is the equivalent of AND NOT. There is no space between the plus or minus sign
 and the keyword.

 NOTE: Most Searche engines require the use of plus and minus rather than AND, OR, and AND NOT.

 +welding +process

 +Saturn -car




 PHRASE SEARCHING

 Surrounding a group of words with double quotes tells the search engine to only retrieve documents in which those words appear side-by-side. Phrase
 searching is a powerful search technique for significantly narrowing your search results, and it should be used as often as possible.

 "John F. Kennedy"      "Walt Disney World" "global warming"

 For best results, combine phrase searching with implied Boolean (+/-) or full Boolean (AND, OR, and AND NOT) logic.

 +"heart disease" +cause            "heart disease" and cause

 The above example tells the search engine to retrieve pages where the words heart disease appear side-by-side and the word cause appears somewhere
 else on the page.

 NOTE ON IMPLIED BOOLEAN LOGIC (+/-): When a phrase search is combined with additional keywords using implied Boolean logic (+/-), you must put a
 plus or minus sign before the phrase as well as the other keywords. If the search involves a phrase with no additional keywords (e.g., "Walt Disney World"),
 the plus sign before the quotes is optional.




GCSE ICT (CCEA) - Assignment B1 Guide




USING THE INTERNET
  Using Boolean Searches

 PLURAL FORMS, CAPITAL LETTERS, AND ALTERNATE SPELLINGS

 Most search engines interpret lower case letters as either upper or lower case. Thus, if you want both upper and lower case occurrences returned, type
 your keywords in all lower case letters. However, if you want to limit your results to initial capital letters (e.g., "George Washington") or all upper case
 letters, type your keywords that way.

 Like capitalisation, most search engines interpret singular keywords as singular or plural. If you want plural forms only, make your keywords plural.

 A few search engines support truncation or wildcard features that allow variations in spelling or word forms. The asterisk (*) symbol tells the search
 engine to return alternate spellings for a word at the point that the asterisk appears. For example, capital* returns web pages with capital, capitals,
 capitalise, and capitalization.




TITLE SEARCH

Field searching is one of the most effective techniques for narrowing results and getting the most relevant websites listed at the top of the results page. A web
page is composed of a number of fields, such as title, domain, host, URL, and link. Searching effectiveness increases as you combine field searches with
phrase searches and Boolean logic. For example, if you wanted to find information about George Washington and his wife Martha, you could try the following
search:

+title:"George Washington" +President +Martha

title:"George Washington" and President and Martha

The above TITLE SEARCH example instructs the search engine to return web pages where the phrase George Washington appears in the title and the words
President and Martha appear somewhere on the page. Like plus and minus, there is no space between the colon (:) and the keyword.

  Using Boolean Searches

  DOMAIN SEARCH

  In addition to the title search, other helpful field searching strategies include the domain search, the host search, the link search, and the
  URL search. The DOMAIN SEARCH allows you to limit results to certain domains such as websites from the United Kingdom (.uk),
  educational institutions (.edu), or government sites (.gov).

  +domain:uk +title:"Queen Elizabeth"

  domain:uk and title:"Queen Elizabeth"


  +domain:edu +"lung cancer" +smok*

  domain:edu and "lung cancer" and smok*




 HOST SEARCH

 The HOST SEARCH comes in handy when you need to find something located at a large site that does not have an internal search engine. With this
 search technique, you can search all the pages at a website (contained in the engine's database) for keywords or phrases of interest.

 NOTE: Because the major search engines do not always log an entire website, use an internal search engine, if the website has one, for best results.

 +host:www.disney.com +"special offer"

 host:www.disney.com and "special offer"

 URL SEARCH

 The URL SEARCH limits search results to web pages where the keyword appears in the URL or website address. A URL search can narrow very broad
 results to web pages devoted to the keyword topic.

 +url:halloween +title:stories

 url:halloween and title:stories
