Explanation / Answer

Please find below answers:

QUESTION 1

Match each term with the statement that best describes it.

Boolean operators : (i) Indicate how keywords are to relate to each other in a search query
Venn diagrams   :    (f) A way to visualize how Boolean operators work
  AND operator    :    (d) One way to narrow a search
   OR operator      :    (h) Used to connect synonyms
  NOT operator     :    (b) Used to exclude words from a search query
Metasearch engine  : (g) A search engine that searches multiple search engines rather than the web itself
  Parentheses         :    (a) Force the order of operation in a Boolean search
         Filters           :     (e) Aids to screen out unwanted web pages         
    Default operator   :   (c) The operator that the engine automatically uses

QUESTION 2

The place where two search results sets overlap is called the __________ of the two sets.

a. intersection
b. union
c. margin
d. combination

Ans: (b) union
The UNION operator is used to combine the result-set

QUESTION 3

When you use the Boolean operator AND to link another keyword to your search query, you find ______.

a. exactly the sane number if web pages
b. more web pages
c. fewer web pages
d. None of the above.

Ans (c) fewer web pages
When you use the Boolean operator AND with different keyword, it returns records that include all of the specified keywords.

QUESTION 4

Equivalent wording for the Boolean OR in an advanced search list box might be __________.

     a. must not contain
     b. all of the words
     c. none of the words
     d. either of the words

Ans (d) either of the words
When you use the Boolean operator OR with different keyword, it returns records that include either of the specified keywords

QUESTION 5

Which is not a standard variation of the Boolean operator NOT?
a. AND NOT
b. NOT MORE
c. The hyphen or minus sigin (-)
d. ANDNOT

Ans (c) The hyphen or minus sigin (-)

QUESTION 6

Which is not a potential downside to using metasearch engines?

a. Usually limited to simple searches
b.Don't search the best search engines
c. Instability
d.Inconsistency

Ans: (a) Usually limited to simple searches
It is not limited to simple searches, rather than it looks for each type of search ranging from easy to complex one.

QUESTION 7

If the order of operation in a complex Boolean search is not forced, the search tool __________.

     a. automatically applies filters to your search
     b. reads the query from left to right
     c. inserts the parentheses for you
     d. returns no search results

Ans:(b) reads the query from left to right
If order of operation is not forced usig complex Boolean search, then it will read the query from left to right.
As by default, if we forcethe order for search, then it will read from right to left,i.e, it will search for the forced string first and then the rest part.

QUESTION 8

A search tool that doesn't recognize Boolean operators as English words in its basic search __________

     a. cannot be used to search with Boolean logic
     b. sometimes allows the Boolean AND and NOT if you use the plus sign (+) and the minus sign (-) instead of words
     c. probably allows Boolean searching from text boxes or list boxes in its advanced search pages
     d. both b and c

Ans: (d) both b and c are true as sometimes boolean operators are usually not recognized as boolean operators but they take it as normal english words to be searched.

QUESTION 9

The part of a URL that can contain a two-letter country code is the ____________.

     a. file
     b. page
     c. file extension
     d. domain

Ans: (d) domain part of URL holds the two letter country code, such as: "www.amazon.ca" where '.ca' stands for country "Canada".

QUESTION 10

Which is not true of metasearch engines?

     a. They search other search engines' indexes
     b. They might skip searching an engine they normally search if that engine is busy at that moment
     c. Their results are always as deep as individual search engines
     d. They are a good place to start when you want to see the top results from several engines

Ans:(C) Their results are always as deep as individual search engines
because a metasearch engine (or aggregator) is a search tool that uses another search engine's data to produce their own results from the Internet. Metasearch engines take input from a user and simultaneously send out queries to third party search engines for results. Sufficient data is gathered, formatted by their ranks and presented to the users. Therefore the search result are not deep enough as the search results of the many search engines.

QUESTION 11

Using parentheses in a complex search tells the search engine that __________.

     a. the words inside the parentheses should be treated as a subset in the search
     b. the part of the search inside the parentheses should be performed first
     c. the words inside the parentheses should be excluded from the search
     d. both a and b

Ans:(d) both a and b as it is a nested search , which enables to search for the part firstly inside the parantheses and then search outside the parantheses.
