button and follow the prompts
Once you have opened the search, you will be viewing a window where you will then type the text that you
would like to search. You can type in a single word, a number, a term, or a phrase. It can be a word, with or
without wild-card characters (*, ?), or any combination of letters, numbers, and symbols. Because you can use
Boolean operators in the text box, you must enclose any search term that includes and, or, or not in quotes.
For more information, go to the Help menu and then to Reader Guide.
To clear the search dialog box and redefine the search, click Clear.
To narrow your search, select one or more of the search options: Word Stemming, Sounds Like,
Thesaurus, Match Case, or Proximity. For information on how these options affect your search
query go to the Help menu then Reader Guide.
Select Search Results. The Search Results box will pop up with the documents that contain matches to your
search query and they will be listed in the Search Results window in order of relevancy. The relevancy ranking
of each document is indicated by an
icon. The degree of fill in the circle in the icon indicates
the probability that the document contains the search information. A solid fill indicates a high probability that
the document contains your search term; an empty circle indicates a low probability that the document con-
tains your search term.
When you use the Proximity option, the closer the matches are within a document, the higher the relevancy
ranking of that document.
You can then double-click a document that seems likely to contain the relevant information, probably the first
document in the list. The document opens on the first match for the text you typed. From this point you can
move from page to page or word to word depending on the preferences that you have set for your search. For
more information on changing the preference go to File>Preferences>Search>Highlight>Display. Click the
