Google is by far the most sophisticated search engine which can also mean that you are going to be presented with millions of search results most of which aren't relevant.and#160;and#8232;and#8232; You can dramatically improve the quality of your search results using one of the many of what Google calls 'query operators' if you understand how to use them.and#8232;and#8232; One 'power tool' that few people know about is the operator for "range" which will filter results in a given numerical range.and#160;and#8232;and#8232; Just by using two periods between two sets of numbers, Google knows to limit your search results to links within those parameters, which it does very well.and#8232;and#8232; For instance, say you're doing a little research for a specific period in time you could type "Russian Revolution" 1800..1900 or when you're shopping for a used smartphone in specific price range, you can type "smartphones $250..$350".and#160;and#8232;and#8232; To further improve your results, try including specific formatting for your numbers (dollars or feet for example)!
