Yes, the search engine checks your search words against all of the words collected from the web site. When a word appears to be misspelled, the search engine looks at all the words it knows and offers you a word that could replace it.
Boolean operators must be typed in UPPER CASE or they will not be recognized as operators.
The Boolean operators 'OR', 'NOT', '-', and '+' may be used in your query.
Using 'AND' is not necessary since all words are searched by default.
The asterisk '*' can be used as a wildcard character.
Use 'OR' when you require only one of the search words to appear in the results. Example: "city OR county"
NOT or -
Use 'NOT' or '-' when you do not want to exclude results that contain a particular term. Examples: "economic development NOT support" or " economic development -support "
Use '*' as a wildcard to search on all words that contain the letters you enter. You must enter a minimum of three letters plus the '*' character. Example: "employ*" would find "employ" or "employer" or "employee"
Use '+' when you require the exact word to appear in all of the results. For multiple words, you must use put a + sign in front of each word that must be exact. Example: search on "+lipitor cholesterol" if you only want to retrieve results with the brand name "Lipitor" and the word "cholesterol", and no results with the generic synonym "Atorvastatin"
There are a few reasons why you could have received this message:
Your word may be misspelled and the search engine can't find a substitute for it. For example, if you had typed in "metakare" when you meant "medicare", the search engine won't be able to recognize it.
