Searching and indexing
Last updated 1/14/2015
3 In the Index Definition dialog box, make any changes you want, and then click the function you want Acrobat to
perform:
Build Creates a new IDX file with the existing information, and updates it by adding new entries and marking
changed or outdated entries as invalid. If you make a large number of changes, or use this option repeatedly instead
of creating a new index, search times may increase.
Rebuild Creates a new index, overwriting the existing index folder and its contents (the IDX files).
Purge Deletes the index contents (the IDX files) without deleting the index file itself (PDX).
Catalog preferences (Acrobat Pro)
You can set preferences for indexing that apply globally to all subsequent indexes you build. You can override some of
these preferences for an individual index by selecting new options during the index-building process.
In the Preferences dialog box under Categories, select Catalog. Many of the options are identical to those described for
the index-building process.
The Force ISO 9660 Compatibility On Folders option is useful when you don’t want to change long PDF filenames to
MS-DOS filenames as you prepare documents for indexing. However, you must still use MS-DOS file-naming
conventions for the folder names (8 characters or fewer) even though this isn’t necessary for the filenames.
Scheduled index updates (Acrobat Pro)
Use the Catalog feature and a catalog batch PDX file (.bpdx) to schedule when and how often to automatically build,
rebuild, update, and purge an index. A BPDX file is a text file that contains a list of platform-dependent catalog index
file paths and flags. You use a scheduling application, such as Windows Scheduler, to display the BPDX file in Acrobat.
Acrobat then re-creates the index according to the flags in the BPDX file.
For more information on scheduling an indexing update, search for BPDX at www.adobe.com/support .
Note: To use BPDX files, in the Preferences dialog box under Catalog, selectAllow Catalog Batch Files (.bpdx) To Be Run.
Moving collections and their indexes (Acrobat Pro)
You can develop and test an indexed document collection on a local hard drive and then move the finished document
collection to a network server or disk. An index definition contains relative paths between the index definition file
(PDX) and the folders containing the indexed documents. If these relative paths are unchanged, you don’t have to
rebuild the index after moving the indexed document collection. If the PDX file and the folders containing the indexed
documents are in the same folder, you can maintain the relative path simply by moving that folder.
If the relative path changes, you must create a new index after you move the indexed document collection. However,
you can still use the original PDX file. To use the original PDX file, first move the indexed documents. Then copy the
PDX file to the folder where you want to create the new index, and edit the include and exclude lists of directories and
subdirectories, as necessary.
If the index resides on a drive or server volume separate from any part of the collection it applies to, moving either the
collection or the index breaks the index. If you intend to move a document collection either to another network location
or onto a CD, create and build the index in the same location as the collection.
