Adobe Acrobat 7 Professional - Manual (Page 557)

Setting Search preferences
You can set the Search preferences, which apply to all subsequent searches, with the Find
toolbar or Search PDF window. Search preferences that affect only searches with the
Search PDF window and not the Find toolbar are noted in the option description.
To set Search preferences:
1. Choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS).
2. Click Search.
3. Set options you want, and click OK.
Ignore Asian Character Width
Finds both half-width and full-width instances of the Asian language characters in the
search text.
Ignore Diacritics And Accents
Finds both cafe and café when you type cafe as the search text, for example. If this option
is not selected, typing cafe does not find café.
Always Use Advanced Search Options
Makes the Advanced Search window the default display for the Search PDF window, and
the Basic Search window isn't available though its options still appear in the Advanced
Search window.
Maximum Number Of Documents Returned In Results
Limits the search results in the Search PDF window to a specific number of documents.
The default value is 100, but you can enter any number from 1 to 10,000.
Range Of Words For Proximity Searches
Limits the search results to those in which the number of words between the specified
words isn't more than the number you specify. You can enter any number from 1 to
10,000.
Enable Fast Find
Automatically generates a cache of information from any Adobe PDF file that you search
with either the Find toolbar or the Search PDF window. The cache then speeds the search
process the next time you search the same file by using the Search PDF window. To avoid
excessively large caches, which can slow overall performance, don't set the value of the
Maximum Cache Size option too high.
Maximum Cache Size
Limits the temporary cache of search information for the Fast Find option to the specified
size in megabytes. The default value is 20, but you can enter any number between 5 and
10,000. When the cache size starts to exceed the size specified, the least-recently used
cache information is deleted.
Purge Cache Contents
Deletes the Fast Find option's entire temporary cache of search information.
