Search options
The Find toolbar provides the following search options in the toolbar's Find Options
menu. The Search PDF window provides these options in either the basic or advanced
search mode:
Whole Words Only finds only occurrences of the complete word you enter in the text box.
For example, if you search for the word stick, the words tick and sticky aren't found.
Case-Sensitive finds only occurrences of the words that are in the case that you typed. For
example, if you search for the word Web, the words web or WEB aren't found.
Include Bookmarks searches the text in the Bookmarks tab as well as in the document.
Include Comments searches the text in comments and in the document. For details about
searching for specific text within the Comments tab, see Finding comments.
Note: The Search PDF window searches all of the areas that the Find toolbar searches and
also searches additional areas by default. (See Searching for words in an Adobe PDF
document.)
