HELP WITH SEARCHING:
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
ocular gene therapy will return more relevant results than typing only ocular.
(Keep in mind, 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 dry will return all documents containing the words dry, Dry, and DRY.
However, typing Dry will search for pages about the Dry Eye.
Use
quotation marks
Use
quotation marks to find words which must appear adjacent to each other, for
example, "macular degeneration." Otherwise, the search results will include the
word macular, and the word degeneration, 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.
Use
field searches
Field
searches allow you to create specific searches for words that appear in a
specific part of a document. A field search can be performed on body text
(body:), title text (title:), alt text (alt:), meta description (desc:), meta
key words (keys:) or URL (url:). The field name should be in lowercase and
immediately followed by a colon. There should be no spaces between the colon and
the search term. Note: The field searches can only be followed by a word or
phrase. Phrases must be contained within quotation marks.
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. |
