Enter quotation marks (" ") around your search terms to search for an Exact Phrase; the system considers this information required and only returns instances in which the full phrase is found.
For example: Enter " java programmer" to return listings where the words java and programmer appear together and in that order.
Enter a plus sign (+) before a search term to search for a Required Word; the system only returns results in which this word is found.
For example: Enter java +programmer (be sure to include a space between the first word and the + symbol) to returns all listings that contain the word programmer. Those listings that also contain the word java will be returned first.
Enter a minus sign (-) before search term to exclude a word; the system will not return any instances in which the Excluded Word appears.
