Ways to improve your search:
1. Be specific
2. Put out common words
3. Put quotes around words that you wants to come together in searches
4. The plus symbol make sure that a word is included in the search
5. The minus symbol make sure that the word is not in the search For an example, if you want to search about how much water mastiff dogs drink a day, you should type in the search engine 'water mastiff dog drink'. That should make the number of result less than if you type 'dog'. Also, you will have better information then if you do that.
