For a proper function of the PDF search the user should press the Cancel button.

Three Panels Of The Window

• The top panel allows the user to specify the searched text/expression and enable/disable additional switches influencing the search process.
• On the left side of the widow is a narrow panel containing as a result of search a list of the pages containing the required information. Clicking on numbers in this listing invokes the appropriate page in the Adobe Acrobat Reader panel.
  Unfortunately Acrobat Reader does not permit highlighting of any text results found on the page. You may find on the page using the Acrobat Reader "Find" function (see Acrobat Reader toolbar).
• The Acrobat Reader (or Adobe Reader) panel shows PDF file content. This panel has it4s own toolbar which allows you to browse within the PDF file. This panel has also an internal Find function which is useful for locating searched phrase on the page. Using the toolbar you can print, move, and zoom in or out on the document. More documentation about controlling the Acrobat Reader plug-in can be found in Adobe Acrobat Reader documentation.

Additional Switches

• Case sensitive - If this switch is enabled, all letters of searched text must exactly match the text in the document including its case. If the switch is disabled, the case of the letters is ignored.
• Regular expressions - If this switch is enabled, the text entered as a searched phrase is treated as a regular expression. Users can use a power of regular expressions (For example it allows using a logical or set operators etc...). The syntax of regular expressions is a subset of commonly used Perl regular expressions. You can find more information on regular expressions and their syntax in chapter Regular Expressions.

Our search technology uses the PdfToText program included in XPDF package. This package must be installed in a subdirectory named XPDF. The PDF documents are being converted to the text form in the background and stored in your TEMP folder. This conversion is executed only once for each PDF file. The conversion may take a moment: please wait until it is finished.

It is possible to find more information about XPDF on www.foolabs.com.
The configuration for the execution of the program PDFTOTEXT.EXE must be included in the Processor Expert Tools.

The Acrobat Reader must be installed on your computer as well.
The PDF Search feature was tested with Acrobat Reader 6.0 and 7.0
