What is the purpose of the "Add exact text" field mapping?

The "Add exact text" field mapping is designed to provide users with the capability to perform searches based on precise matches of text, without the influence of stemming. Stemming reduces words to their base forms, meaning that variations or inflections of a word might also be included in search results. By utilizing the "Add exact text" field, users can ensure that only the exact phrases or terms they have inputted will be matched in the search. This feature is particularly important in situations where the integrity of the phrase is crucial to the search's relevance, such as legal documents, technical specifications, or any context where word choice is critical.

The other options do not accurately describe the functionality of this field. For instance, creating a summary of text content or combining related fields pertains to different aspects of data manipulation and presentation, while excluding specific terms is a separate operation focusing on filtering out unwanted results rather than matching exact phrases.
