Assembly

States which part of a message the searchable text came from, or why the message yielded none.

public enum ExtractedEmailTextSource

Fields

BodyNotExtracted = 4

Extraction never ran for this message, so its body has contributed nothing either way.

This is the state of a message whose raw MIME was never stored because it exceeded the size limit, and of one whose stored MIME no reader could parse. It is never the source of an ExtractedEmailText, which only ever describes a message something did read; it exists so such a message is still indexed on what its envelope reported instead of being findable by nothing at all.

DerivedFromHtmlBodyPart = 1

The text was derived from an HTML body because the message offered no plain-text alternative, which is lossy.

EncryptedBody = 3

The body arrived inside a cryptographic envelope, so no text could be read from it here.

NoTextualBodyPart = 2

The message carried no readable textual body at all.

PlainTextBodyPart = 0

The text is what a genuine text/plain body part carried, so nothing was inferred from markup.

Remarks

The absent cases stay distinct because they answer different questions about a message that returns no search hit on its body. A message nobody encrypted and that genuinely carried no words is a complete record; an encrypted one is a body that exists and cannot be read here, and merging the two would turn a known gap into a silent one.
