Searching Adobe PDF index files
Note: This feature is not available unless you have the full version of Adobe Reader.
An Adobe PDF index is a specially prepared file that catalogs multiple Adobe PDF files 
and is available through Search. If a full-text index is available for a set of Adobe PDF 
documents, you can search the index for a word rather than searching each individual 
document. A full-text index is an alphabetized list of all the words used in a document or, 
more typically, in a collection of documents. 
Searching an index is much faster than searching all the text in the documents. An index 
search produces a results list with links to the occurrences of the indexed documents. 
Selecting the Match Whole Word Only option when searching indexes significantly 
reduces the time taken to return results.
Note: To search an Adobe PDF index, you must open Adobe Reader as a stand-alone 
application, not within your web browser. In Mac OS, indexes created with some older 
versions of Acrobat are not compatible and cannot be searched in Adobe Reader 7.0, 
using the current Search feature, until the indexes are updated.
To search an index:
1.  At the bottom of the Search PDF window, click Use Advanced Search Options.
2.  Type the word you want to find.
3.  For Look In, select Select Index.
4.  If you want to view information about an available index, select the index name, click 
Info, and then click OK. The information includes the title, information provided by the 
builder, location, the build date, creation date, number of documents in the index, and the 
index status.
5.  Select the index you want to use, or click Add, locate the index file (.pdx) you want, and 
then click Open.
6.  In the Index Selection dialog box, click OK, and then proceed with your search. (See 
.)
 Once you've selected an index to search in, you can choose Currently Selected 
Indexes in step 3, instead of the Select Index command, to select that particular index to 
search.
