About searching

You can also refine the scope of the search:

• Current document, or only the comments in the document (by calling the search from the Comments panel).

• Selected documents within a PDF portfolio.

• A specified folder (called "folder search").

  A folder search lets you search one folder (with or without subfolders) or limit the search according to values in standard fields (such as author, title, subject, keywords) of the PDF Properties. See About search options.

• Search with the currently selected indexes.

• Search with another index.

  An index search supports greater speed because it uses a pre-built index. It also gives more flexibility; letting you expand the search by defining a set of search folders and subfolders and letting you narrow the search, using not only standard PDF Property fields, but also custom defined fields with values you define.

For any of the above, specify commonly used search criteria such as Match Case or Match whole word only. In addition, specify whether to include comments and bookmarks.

When performing searches in multiple documents, enter the following logical operators to refine your search:

• And: "&"
• Or: "|"
• Not: "~"
• Parentheses: "(" and ")"

Use parentheses to define the order in which Boolean operators are performed. For more information, and diagrams showing the effects of these operators, see Boolean operators.
