Check Spelling - Make sure your search terms are spelled correctly. The search engine will attempt to find words that sound similar to your search terms, but it is always best to try to spell the search terms correctly.
Use Multiple Words - Use multiple words when performing your search. The search results will return more refined results from several words than from a single word. For example, typing Little Miami river will yield more relevant results than typing only Miami. Keep in mind that relevant results are returned even if they don't contain all query terms.
Use Similar Words - The more similar words you use in a search, the more relevant results you will get back.
Use Appropriate Capitalization - Capitalize proper nouns. Lowercase words will match any case. For example, typing search will return all documents containing the words search, Search, and SEARCH. However, typing Search will only return pages that contain the word Search.
Use Quotation Marks - Use quotation marks to find words which must appear adjacent to each other, for example, "Corvette museum". Otherwise, the search results will include the word museum and the word Corvette, but not necessarily in that order. The words may appear anywhere, and in any order, within the document.
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.
