1. Use quotation marks to search accurately (” “)

When we search for specific content, we can put double quotes around the index content to make Google search less guesswork. At this point, Google will search for exactly what we’re looking for. Only results with exact content are displayed in the search results.

For example, searchlearn JavaScript array, the search engine will search for content containing these three words in any order:If the content is enclosed in quotation marks, the search is accurate:

2. Exclude content with a hyphen (-)

Sometimes, we can use a hyphen to exclude searches that have multiple meanings or that we don’t want to see related to a particular piece of information.

For example, search JavaScript to exclude relevant content from Wikipedia:

3. Fill content with an asterisk (*)

You can use asterisks to fill in the Spaces between text, for example, if you remember parts of a text and forget others during a search.

For example, if we forgot the second word of the undo commit command in Git, we could search it like this:This is the asterisk wildcard in place of the indeterminate content to let Google do the job.

4. Search the specified range (…)

Can use… To search for the contents of a specified numeric range, which can be year, version, and so on.

For example, search:JavaScript in 2021… 2022.

5. Search for the specified site (search 🙂

You can use the **search format to search for content within a specified site.

For example, in W3C search:search: w3schools.com javascript Array

6. Search for specified fileType contents (fileType)

You can use filetype to get search results that determine the filetype. You can use this method to search for e-books, documents, and other types of content.

For example, search:React ebook filetype:pdf As you can see, all of the search results are pages containing PDF.

7. Find multiple keywords (AND)

If we are looking for something that contains multiple keywords, then AND comes in handy.

For example, search:React AND CSS

8. Look for one of the keywords (OR)

You can use OR to query for one of multiple keywords.

For example, search:React OR Vue

9. Query keyword definition (Define)

You can use the Define keyword to look up the definition of a search term.

For example, search:Define: JavaScript

10. Search for related content (+)

If we want to search for multiple related keywords, we can use the plus sign to connect multiple related keywords.

For example, search:CSS style+React

11. Find similar Websites (Related)

You can use the related keyword to query for sites similar to the specified site.

For example, search:related: w3schools.com

12. Search for specified site content (site)

You can use the site keyword to search for content in a specified site.

For example, search:site: github.com React

13. Search for specified time ranges (before, after)

You can use after to search after the specified time and before to search before the specified time.

For example, search:after: 2021 learn react
