To locate ads on the system that contain specific keywords, you may enter
    the terms you are looking for in the Keyword Search text box located at the
    bottom of most pages throughout the system.
    Keyword Search (Any)
    To perform a broad search of all ads posted, enter your search terms and
    select the option to locate any ad that contains "any of my keywords". This
    is the simplest of all searches and may return a large number of matches
    depending upon your keyword entered. Further narrow your search by selecting
    a specific category.  For best performance and accuracy, omit words
    such as and, or, it, the, etc.
    Keyword Search (All)
    To further narrow your search, you should select the option to find "all
    my keywords" in an ad. This will only return ads which contain every keyword
    you have entered into the keyword text box area. For example: Entering the
    keyword Honda would return all ads which contain the keyword Honda. However
    by entering the keywords Honda Accord, only ads containing the keywords
    Honda Accord would be returned. For best performance and accuracy, omit
    words such as and, or, it, the, etc.
Keyword Search (My Exact Phrase)
    If you know exactly what you are looking for and want to find a specific
    phrase matched in an ad, enter the phrase your are looking for and select
    the option to find My Exact Phrase.  This will return results that
    contain only the phrase you are looking for.  For example, entering the
    phrase The Blue Moon would only be found if it is entered into the ad
    exactly that way.
