By default, all the text is indexed as not belonging to any field. Whenever a begin tag that appears in the stream of text matches a definition item in the document model that is currently active, the text between the begin tag and its corresponding end tag is treated according to that definition term. For example, as an indexed field, an excluded field, or as an attribute or both.
If no matching definition exists, the begin tag and its corresponding end tag are ignored.
As Outside In filters automatically recognize the format and code page of the document, the CCSID specification has no effect. If the Outside In filters are unable to determine the correct format and code page, the document is treated as an ASCII file.
