How does a dtSearch using the NOT operator produce different results compared to a Keyword search?

The correct response highlights that a dtSearch using the NOT operator combines text from all indexed fields into a single result. This means that when the NOT operator is applied in a dtSearch, it negates specific terms from any of the indexed fields across the documents, effectively filtering the results to exclude certain content.

In the context of a keyword search, however, the search engine typically focuses on specific fields rather than a comprehensive index. This distinction is significant because it influences how results are presented and what content is ultimately included or excluded based on the criteria defined by the search.

In a dtSearch, the implementation of the NOT operator impacts the overall document retrieval by negating the presence of specified keywords across all searchable fields, leading to a more refined and potentially different set of results than those obtained through a keyword search, which may not encompass that broader search field methodology.
