Make 200% use of Google searches: Advanced Google search tips that you can use behind closed doors

Gone are the days when lack of information on the Internet was a problem. Nowadays, we live in an era where competitiveness lies in the ability to quickly and accurately retrieve only the ‘useful information you really want’ from a vast sea of ​​information. We encounter the Google search bar every day, but most people just type in a few words. Google is a much smarter and more powerful search engine than you might think. Today, we will introduce 'advanced Google techniques' that will go beyond simple searches and maximize the efficiency of information search.

The core of Google search, utilizing search operators

A search operator is a special symbol or command that is entered along with a word in the Google search box to control search conditions in detail. Just by knowing these few symbols, you can cut down on wasting time by more than half with irrelevant search results.

1. Words that must be included: double quotation marks (" ")

This is the most basic and useful operator. If you enclose your search term in double quotation marks, Google will only find results that exactly match the phrase without any errors.

• Example: If you type smartphone battery management, documents with three scattered words will appear, but if you type "smartphone battery management", only documents containing exactly those sentences will be searched. It's very powerful when troubleshooting specific error messages or finding the title of a song by its lyrics.

2. Excluding specific words: Minus sign (-)

I use it when search results keep showing information I don't want. Just place a minus sign in front of the word you want to exclude. (A space must be placed before the minus sign and a space must be added after it.)

• Example: If you search for 'Apple -Apple -Juice', only results related to the IT company Apple will be shown, excluding information about apples, an edible fruit.

3. Search only within a specific site: site:

When a website has a lot of great information, but the site itself has a poor search function, you can borrow Google's powerful search algorithm. Enter in the format site:domain search term.

• Example: If you search for site:wikipedia.org artificial intelligence, only documents related to 'artificial intelligence' within the Wikipedia site will appear as search results. This is essential when searching for materials on a specific community or government agency site (site:go.kr).

4. Search by specifying file extension: filetype:

This is useful when you want to immediately download only document files of a specific format, such as papers (PDF), presentations (PPT), or data (Excel).

• Example: If you search for climate change report filetype:pdf, only download links for PDF documents containing the word 'climate change report' will be listed in the search results, not web pages.

5. Words with similar meaning at once: Tilde (~)

Even if you don't have to type in synonyms or words with similar meanings, Google automatically searches for related concepts.

• Example: If you search for ~cheap laptop, information related to laptops with meanings such as 'cheap' as well as 'cheap' and 'cost-effective' will be displayed.

Small tips to improve your search

In addition to operators, the Google search bar itself can serve as a variety of utility tools. Get to know the functions that can be solved immediately in the search box without having to open a separate app or access another site.

Use the search bar as a calculator and unit converter

If you type simple arithmetic operations directly into the search box, a calculator will pop up and give you the correct answer. (e.g. 15 * 450 + 20) But even more useful is the unit conversion function. When purchasing directly from overseas or watching foreign news, if you see an unfamiliar unit, immediately ask about it in the search box.

• Example: If you naturally enter '150 dollars in won', '50 inches cm', '30 degrees Celsius in Fahrenheit', Google will convert it to the most up-to-date exchange rate and accurate figures and display them at the top.

Filter only information within a specific time period

When searching for fields where up-to-date information is important, such as IT technology or news, outdated information from the past becomes a hindrance. After searching, click 'Tools' in the menu right below the search box under the Google logo. You can open the drop-down menu labeled 'All dates' to filter out only the most recent documents using 'Last hour', 'Last month', or 'Set a date range'. This is an essential habit when keeping up with the latest trends.

Conclusion

The power of the search operators introduced earlier is doubled when combined with each other compared to when used alone. For example, if you search for "big data analysis" site:go.kr filetype:pdf, you can filter out only 'big data analysis-related PDF documents published by Korean government agencies' in just 1 second. Typing these commands may feel a little cumbersome at first, but once you get used to it, the speed and quality of your information retrieval will improve beyond compare.
