Search features preferences

In the Preferences dialog box under Categories, select Search.

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 the search terms with any variation of the alphabetical characters. For example, typing cafe finds both cafe and café. Likewise, typing café finds both versions. If this option isn’t selected, typing cafe doesn’t find café, and vice versa.

Always Use Advanced Search Options

Makes the advanced options available in the Search window, in addition to the basic options.

Show Document Title In Search Results

Displays document titles in search results. If a document does not have a title, displays the filename. When unselected, displays filenames in search results.

Enable Search Highlights From External Highlight Server

Enables highlighted search results when using an external server, such as a web-based search mechanism.

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 500, 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 search terms isn’t greater than the number you specify. Accepts a range from 1 to 10,000.

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.
