Search Tips


Simple Search

Starting a Search
Type a word or phrase and click the "Search" button or press the Enter key. Searches for single words or simple phrases may match our Key Site feature, pointing out the primary site for information on that term. If you are searching for a phrase, remember that the order of words in the phrase is important.

Example: Acuvue (simple one word search)
Example: Disposable lenses (one phrase, no commas needed)
Example: acuvue disposable lenses (one phrase, order is important)

Adding search terms
To make your results more specific, use multiple search terms, separated by commas. Each search term may be a single word or a phrase. The commas tell the search engine "Find as many of these terms as possible, in any order."

Example: soft, disposable, 2 week (three words, any order)
Example: soft, disposable lenses (a word and a phrase)
Example: contact lenses, shipping charges, privacy statement (three phrases)

Capital letters
Capital letters do change your results because simple searches are case-sensitive. "WebObjects" and "webobjects" do not get the same search results. If case insensitivity is required, use all upper or all lower case. The rule is that mixed case querys are case sensitive, all upper or all lower case searches are case insensitive.

Our search engine uses stemming to automatically include related variations of your search term. If you search for update, you will also find "updated", "updates", "updating" and so on. Every word in a search phrase is stemmed unless quotation marks are used.

Quotation Marks
Use quotation marks around your search terms to find exact matches.

Example: Announce (matches announcement, announcing, and announced)
Example: "Announce" (matches only announce)

Asterisk (*) and Question Mark (?)
Use asterisks and question marks when you don't know the exact spelling of a word or want to match many words which begin the same. Question mark replaces a single unknown character.

Example: acuvue? (matches acuvue, acuvue 2, acuvue toric)

Asterisk matches multiple unknown characters and can broaden your search. Remember that stemming (described above) may help to broaden searches for common words. If you are looking for an even broader range of words, asterisk will find words which are unrelated but start the same. (cat* matches cat, cats, catapult, and catch)

Example: cat* (matches cataracts, and catalog)

And, Or, Not
Use "or" to broaden your search. Use "and" and "not" to narrow your search.

Example: Biomedics or Acuvue (matches either search term)
Example: Acuvue and Toric (match must include both terms)
Example: Acuvue not Acuvue Toric (match first term, exclude second term)
