VOID expressions return no value but are used to
perform other work. The VOID PARSE_DOC expression obtains metadata and extracts
text from documents and adds the metadata and document text in the form of
property values to a record.
Both text/plain and text/html files can be extracted from documents by
this expression; other file types are passed to the Document Conversion Module
converters for parsing. See "Implementing the Endeca Crawler" in the
Forge Guide for a description of each generated
property that
PARSE_DOC adds to the record.
The following list describes the optional expression nodes that can
