1. Search with specific words. For example "goldfish" and "salmon" give us more specific concepts than "fish". Use the search words as exactly possible.
2. Use minus sign to exclude the information you don't need. For example if you search for "mouse" there will be two meanings: the computer mouse and the animal mouse. You need to put the minus sign in front of the word "computer". You will only get animal mouse.
3. Use quotation marks around the words that appear together. For example if you're searching for "gold fish", the computer will give "gold" and "fish" that appear together, one after the other. If you don't use quotation marks, the computer will give words that doesn't appear together.
4. Don't use too many words. You don't need to write too much sentences. The computer will get confused. It doesn't think with our sentences. It thinks with key words only.
5. Use plus sign to include the exact words you want. For example if you want to search for "rabbit", the computer will also give synonyms like "hare" or "bunny". So there's too much information. You don't need all this if you're only searching for the word "rabbit".
