When Info Items are created for text, Outlook objects, or document types listed below, Ultra Recall parses the information for text or keywords automatically. This occurs regardless of whether a document or object is stored or linked in Ultra Recall. These automatically generated keywords are referred to as Auto-Generated keywords.
Keywords can be retrieved for the following file types:
| • | MHT (web pages saved by Internet Explorer) |
| • | Microsoft Office documents (including Word, Excel, and Powerpoint) |
| • | Microsoft Outlook (messages + attachments for known document types, contacts, appointments, tasks or notes) |
| • | Firefox/Netscape/Mozilla bookmarks |
| • | Email messages (Mozilla Thunderbird, Postbox, Outlook Express, The Bat!, Windows Mail, and Windows Live Mail messages and news posts and any MIME file, including attachments for known document types) |
| • | Pictures and other documents with summary information |
| • | Text (system code page, UTF-8 and UTF-16 encodings) |
| • | ZIP (any supported file types found in the ZIP file) |
| • | TIFF documents containing OCR text (Microsoft Office Document Imaging) |
Notes:
| • | Keywording of Outlook items, PDF files, and ZIP files available in Professional edition only. |
| • | Auto-generated keywords are displayed only if full-text search enhancements are disabled. If full-text search enhancements are enabled, this list will always be empty (document text will still be stored and searched, with additional capabilities). |
Auto-generated Keywords can't be manually added (see User-Defined Keywords) but can be deleted (they are automatically replaced when the Info Item is Synchronized).
The following rules are used by Ultra Recall to retrieve Auto-Generated keywords:
| • | Only files whose extension (or the extension for its content type) is included in the File extensions to keyword user option are keyworded. |
| • | Numbers are included only when the related user option is checked. |
| • | Words two characters or longer (up to 15 characters in length; longer words are truncated) are included. |
| • | Alphabet characters and $ _ @ characters are included. |
| • | # - + % & characters are included if not the beginning of a word. |
| • | . and : characters are included if not at beginning or end of a word. |
| • | The same character repeated more than 3 times contiguously is not keyworded. |
| • | All other characters are excluded (for example, ! ` ~ ; , ' " < > ^ ( ) { } | / \ ). |
