If email headers are enabled when creating a conceptual index, which fields are removed?

When email headers are enabled during the creation of a conceptual index, the fields that are typically removed include the “To,” “From,” and “Date” headers. This is done to streamline the indexing process and focus on the content of the emails rather than on routing or metadata information that might not be relevant for analytical purposes.

By removing these specific headers, it allows the index to focus on the substance of the communication, which can better support the goals of data analysis and retrieval. These elements, while informative in a direct email context, do not contribute meaningfully to the conceptual indexing, which aims to group content based on themes, topics, or other contextual relevance rather than sender/receiver or chronological information.

This approach is particularly useful in scenarios where the emphasis is on analyzing the text and contexts of email content, making the insight gained from the data more impactful.
