Searching and indexing
Last updated 4/7/2015
Enable Fast Find Generates a cache of information from any PDF that you search. This cache reduces subsequent
search times for that PDF.
Maximum Cache Size Limits the temporary cache of search information for the Fast Find option to the specified size
in megabytes (between 5 and 100,000). The default setting is 100.
Purge Cache Contents Deletes the Fast Find option’s entire temporary cache of search information.
Creating PDF indexes
Create and manage an index in a PDF
You can reduce the time required to search a long PDF by embedding an index of the words in the document. Acrobat
DC can search the index much faster than it can search the document. The embedded index is included in distributed
or shared copies of the PDF. Users search PDFs with embedded indexes exactly as they search those without embedded
indexes; no extra steps are required.
Add an index to a PDF
1 With the document open in Acrobat DC, choose To ol s > Index.
The Index toolset is displayed in the secondary toolbar.
2 In the secondary toolbar, click Manage Embedded Index.
3 In the Manage Embedded Index dialog box, click Embed Index.
4 Read the messages that appear, and click OK.
Note: In Outlook and Lotus Notes, you have the option of embedding an index when you convert email messages or
folders to PDF. This is especially recommended for folders containing many email messages.
Update or remove the embedded index in a PDF
1 Choose To o ls > Index.
The Index toolset is displayed in the secondary toolbar.
2 In the secondary toolbar, click Manage Embedded Index.
3 Click either Update Index or Remove Index.
About the Catalog feature (Acrobat Pro DC)
You can define a specific group of PDFs as a catalog and create a unified index for that entire collection of documents.
When users search the cataloged PDFs for specific information, the index makes the search process much faster.
When you distribute the collection on a CD, you can include the index with the PDFs.
You can catalog documents written in Roman, Chinese, Japanese, or Korean characters. The items you can catalog
include the document text, comments, bookmarks, form fields, tags, object and document metadata, attachments,
document information, digital signatures, image XIF (extended image file format) metadata, and custom document
properties.
