Normally when you do a google search punctuation marks and symbols are completely ignored. For example the following symbols are never registered: ¶, £, €, ©, ®, ÷, §, (), ?, ! However, in special circumstances some symbols do get included in a search. The plus symbol, +, is usually not registered but exceptions include when you are search for the programming language C++ or when you are searching for Google’s social networking site, Google+. A list of these exceptions can be found here.
On its own, the dollar symbol, $, is ignored, but Google picks it up when it is included with numbers. This means that searching for 500 and $500 will give you different results. On its own this is good to keep in mind when you are searching google. However I recently discovered a neat way to apply this when combined with Google’s number range operator..
If you want to search number ranges in Google you do so by separating two numbers by two periods. For example searching 2007..2011 will return pages containing 2008, or any number in that range.
You can also include a ranges inside a set of quotes for example “4800..5400 Baltimore Ave.” will return any addresses on Baltimore Avenue in side that range, such as 4987 Balimore Ave. Now all you need to do is insert the name a specific city, and you will find all sort of results on properties in that range.
