Google Search Tip 5: Use two dots to define a number range
You can define a number range for any type of number such as the year, miles per gallon, or price by placing two dots between the numbers. There is no space before or after the two dots. For example, type french films 1960..1965 to get search results from 1960 to 1965.
Don’t use the dash (-) like you would in a regular sentence! Remember, a dash will omit results in Google.
