How should a developer configure the Search Dictionaries Dashboard to show only car accessories while excluding others?

To configure the Search Dictionaries Dashboard to display only car accessories while excluding others, creating a Common Phrase Dictionary entry with just "car accessories" is the most effective approach. This method directly targets the relevant terms without introducing any potential noise or conflicting searches.

When utilizing a Common Phrase Dictionary entry, the developer can ensure that searches exclusively focus on the specified term, which is "car accessories." This creates a clear and straightforward association in the search algorithm, allowing it to return results specifically related to car accessories, effectively filtering out unrelated products.

Choosing a synonym or common phrases that include exclusions can complicate the search results and does not guarantee that only the desired items will be highlighted. This can lead to ambiguity and possibly even include items that are not relevant, hence why the other options do not adequately address the requirement for exclusivity in search results.
