구글 검색 팁 (Google Search Tips)

구글 검색을 잘 활용하면 유용한 정보를 찾는 시간을 절약할 수 있습니다.

생각보다 구글 검색 팁에 대한 내용이 없길래... 정리해 봅니다.


원문 만큼 쉽게 설명하지를 못 했네요..

내용이 빈약하여 계속 업데이트할 예정이므로 불펌은 금합니다.

좀 더 내용정리 후 자유롭게 펌할 수 있도록 하겠습니다.^^;;


1. 기본적으로 알아야할 것 들
1) 구글은 대소문자를 구분하지 않는다.
(Google, GOOGLE, GooGle 의 검색 결과는 동일하다.)
2) 하지만 '구글 검색 연산자'는 대소문자를 구분한다.
(구글 검색 연산자 OR를 사용하기 위해서는 꼭!! 대문자를 사용해야 함.)
(사람 OR 사람들 (O), 사람 or 사람들 (X))
3) 구글은 기본적으로 모든 검색어가 포함된 페이지를 검색한다. 검색어의 순서도 중요하다.
4) 구글은 중복된 검색어들은 제외 시킨다.
즉, 'the' 가 여러번 나온 문장을 검색해도 the는 한개만 있다고 가정하고 검색한다.
5) 일부 구글 검색 연산자는 혼합해서 사용할 수 있지만
일부 구글 검색 연산자는는 단독으로 사용해야만 한다.

2. 기본적인 검색 연산자
1) +
: +표시된 검색어는 검색결과에 꼭 포함시킨다.
검색어 중 꼭 포함시키고 싶은 검색어를 사용할 때 사용.
ex) 대한민국 +한국
=>'한국' 이 반드시 포함된 검색결과를 보여준다.

2) -
: -표시된 검색어는 검색결과에 제외 시킨다.
ex) 대한민국 -한국
=> '한국' 제외된 검색결과를 보여준다.

3) OR
: 주어진 검색어 중 하나 이상의 검색어가 포함되어 있는 검색결과를 보여 준다.
반드시 대문자를 사용해야 하며 'OR' 대신 ''도 사용 가능하다.
ex) 대한민국 OR 한국, 대한민국 한국
=> 대한민국, 한국 둘 중 한개만 포함되도 검색된다.

4) ” “
: 인용 부호에 포함된 구문을 검색결과에 꼭 포함시킨다.
+와 비슷한지만 인용 부호에 포함된 구문은 순서, 띄어쓰기가 모두 일치하는 검색결과를 보여준다.
ex) "독도는 우리땅이다."
=> 위 구문의 띄어쓰기, 순서가 모두 일치되는 페이지를 찾아 준다.

5) ~
: 유의어를 검색할 수 있으며 검색어 도움말 또는 가이드도 같이 표시된다.
ex) 독도 ~땅
=> 일부 단어만 기억하고 있을 때 사용하면 유용할 듯 합니다.

6) *
: 모든 단어를 의미함.
ex) "외로운 섬하나 *"
=> '외로운 섬하나 새들의'과 같은 가사 검색시 사용할 수도 있겠네요..
'외로운 섬하나'가 반드시 포함되고 반드시 뒤에 한 단어 이상이 더 붙는 문장을 찾아 보여줍니다.

7) ..
: 숫자의 범위를 지정하여 찾을 때 사용된다.
ex) 2..50 인디언
=> '2 부터 50 사이의 숫자'가 포함되고 '인디언'라는 단어가 포함된 페이지를 찾아 줍니다.
