Using the plus in your searches
adding a plus before your search word or phrase tells the search engine that it must have the item in your search results. if you use no operators, you are implicitally giving the search engine permission to include any or all of hte words in your search condition. When you add a plus immediately before a word, you are saying "must have"... the search engine will discard pages without that item.
As you begin to construct more complex searches, you can combine the plus, minus and quotes to really direct the search engine to do much of the manual searching that you perform today....
Example
disneyland hotel handicapped access
this search will bring back missions of pages, with any of the words above.
+disneyland +hotel +handicapped +access
this will bring back only those pages with all of the words. You will probably see an immediate 10-100 X reduction in the number of pages and the quality will skyrocket.
