6. ความหมายของ “Search Engines”
Search Engines:
Search engines are programs that search documents for specified keywords
and returns a list of the documents where the keywords were found. A search
engine is really a general class of programs, however, the term is often used to
specifically describe systems like Google, Bing and Yahoo! Search that
enable users to search for documents on the World Wide Web.

28. Keep it simple! Start by typing the name of a thing,
place, or concept that you're looking for.
For example:
puppy training tips
london dinner cruise
pasta recipe
การเว้นระยะเท่ากับเชื่อมด้วยคาว่า AND
30. Phrase search (“……")
Search for an exact word or phrase/set of words.
By putting double quotes around a set of words, you are telling Google
to consider the exact words in that exact order without any change.
This option is handy when searching for song lyrics or a line from
literature.
For example, a search for ["imagine all the people"].
33. Terms you want to exclude (-)
Add a dash (-) before a word or site to exclude all results that include
that word.
This is especially useful for synonyms like Jaguar the car brand and
jaguar the animal.
[ jaguar animal -car ] or [ pandas -site:wikipedia.org ]
Tip: You can also exclude results based on other operators, like excluding all
results from a specific site.
36. Fill in the blanks (*) หรือ Wildcard
Use an asterisk (*) within a query as a placeholder for any unknown or
"wildcard" terms.
Use with quotation marks to find variations of that exact phrase or to
remember words in the middle of a phrase.
[ "a * saved is a * earned" ]
39. The OR operator
If you want to search for pages that may have just one of several words,
include OR (capitalized) between the words.
Without the OR, your results would typically show only pages that
match both terms.
[ olympics location 2014 OR 2018 ]
Tip: Enclose phrases in quotes to search for either one of several phrases.
[ "world cup 2014" OR "olympics 2014" ]
