Fields (metadata) that dtSearch automatically detects and indexes in documents.

The dtSearch Engine automatically detects fields in the following file formats:

Microsoft Word, Excel, PowerPoint

HTML
META tags; <TITLE> is indexed as HtmlTitle field; <H1>, <H2>, <H3> are indexed as HtmlH1, HtmlH2, HtmlH3, etc.
XML
All fields
DBF
All fields
CSV
All fields (CSV, or comma-separated values, files must have a .csv extension, a list of field names in the first line, and must use tab, comma, or semicolon delimiters)
PDF files
Document Properties
WordPerfect

To prevent fields from being indexed in documents, set the dtsoFfSkipDocumentProperties flag in Options.FieldFlags. This setting does not affect CSV, XML, or DBF files. 

The NTFS file system supports file properties for other formats. Set the dtsoFfShowNtfsProperties flag in Options.FieldFlags to have the dtSearch Engine check for and index these properties, where present.
