Why do you need to improve your Google search? Most of the times, we find the information we need quite fast. Sometimes we may spend a lot of time looking for information. By using these operators, you will hopefully find what you search for a lot quicker and easier.
The or | operator is helpful for searching for something that you are not quite sure what the name was. You can either write "or" or use the pipe sign |. For example, search for Tom Bill, and you will get a lot of Tom and Bills and Tom Bill himself. Write Tom | Bill, and you will get Tom Cruise and Bill Gates as results.
You can include exact words with the quotation marks. Using quotation marks are useful when you want to make sure that you include a certain word in the search. Searching for best burger in Helsinki 2015 will not yield as many results from 2015 as best burger in Helsinki "2015" would. You can also write the whole search sentence in quotation marks. Google will thus include just results with the whole matched sentence. Searching "best burger in Helsinki 2015" reveals that Kämp had the best burger 2015.
Different searches can yield different results depending on what context the words are using. If you are a Star Wars fan like me, you can search for Star Wars -"episode IX" to exclude the upcoming episode.
You can search within site with the site: operator. For example, say that you want to find everything related to Tkinter on my website. You write site:connysoderholm.com Tkinter, and Google now lists all results with Tkinter from my site.
You can use the * sign to replace a word in your search. Searching for fastest * in Europe reveals the fastest roller coasters, internet, companies, and cars in Europe.
Don't know the exact number? Use the number to number search. A search for tablet $700..$900 shows us some various results for tablets in the price range of 700 to 900 dollars.
You can write related: to see similar sites to the one you search for. Typing for example related: foreship.com shows related content to the Foreship website.
