Here are some additional tips to help ensure that you get the best search results:

1. Check spelling
   Make sure your search terms are spelled correctly. If Sound-Alike Matching is turned on, the search engine will attempt to find words that sound similar to your search terms, but it's always best to try to spell the search terms correctly.
   
   
2. Use multiple words
   Using multiple words will return more refined results than a single word. For example, typing our free service will return more relevant results than typing just service. (Keep in mind that relevant results are returned even if they don't contain all query terms.)
   
   
3. Use appropriate capitalization
   Capitalize proper nouns, and remember that lower-case words will match any case. For example, typing search will return all documents containing the words search, Search, and SEARCH. Typing Search, however, will instruct the search engine to look only for the capitalized word.
   
   
4. Use quotation marks
   Use quotation marks to find words which must appear adjacent to each other, for example, "our pledge to you." Otherwise, the search results will include the word our, pledge, to, and the word you, but not necessarily in that order. The words may appear anywhere, and in any order, within the document.
   
   Note: if you are using the Advanced Search Form with radio buttons for "any," "all," and "phrase," then quotes can only be used when the "any" radio button is selected. Quotes are ignored if the "all" or "phrase" radio buttons are selected.
   
   
5. Use plus (+) or minus (-)
   Use a plus sign when your search term or phrase must appear in the search results. Use a minus sign to indicate undesirable term(s). The plus sign tells the search engine that a certain word or phrase is required in the search results, and a minus sign indicates that a word or phrase must be absent in the search results.
   
   Note: A phrase must be contained within quotation marks. Leave no spaces between the plus or minus sign and the term.
   
   Note: if you are using the Advanced Search Form with radio buttons for "any," "all," and "phrase," then plus and minus can only be used when the "any" radio button is selected. Plus and minus are ignored if the "all" or "phrase" radio buttons are selected.
   
   
6. Use wildcards
   Wildcard searches can expand the number of matches for a particular request. The * character is used as the wildcard character.
   
   For instance, searching for wh* will find the words what, why, when, whether, and any other word that starts with wh.
   Searching for *her* will find the words here, whether, together, gathering, and any other word that contains her anywhere in the word.
   
   Wildcards may be combined with the standard plus (+) and minus (-) modifiers, quotes for phrases, as well as the field search specifiers.
   +wh* -se*ch will find all pages which have a word that starts with wh and which does not contain a word that starts with se and ends with ch.
   "wh* are" will find the phrases where are, what are, why are, etc.
   
   
7. Word order does not matter. For example, searching for "California red wine" and "wine california red" will produce the same results.
   
   
8. It is not necessary to use Boolean terms, such as "and", "or", and "not".
   
   
9. It is not necessary to phrase your search in the form of a question. For example, you do not need to enter "Where can I find information about tourism in Hawaii?". Instead, just enter "Hawaii tourism".
   
   
10. Be as specific as you can. However, if you get few or no results, try making your search more general. For example, instead of using specific product names, try using the name of the product category and see if you get more results.
    
    
11. Try using synonyms. If the search term you entered produces few results, try using a synonym or more common term that means the same. For example, instead of searching for "television programs", try the more common expression "tv shows".
