In a SQL query, what function is used to sort fuzzy text search results by their relevance?

The function used to sort fuzzy text search results by their relevance is SCORE(). This function specifically evaluates the relevance of each search result based on various factors, returning a score that indicates how well each result matches the search criteria. When performing a fuzzy text search, using SCORE() allows for results to be ranked or prioritized according to their degree of relevance, making it much more effective in providing users with the most pertinent data.

In contrast, while ORDER BY is used to sort results in general SQL queries, it does not inherently take search relevance into account. Similarly, RANK() can be utilized to assign ranks based on computed values, but it is not specifically designed for sorting search results based on their relevance scores. SORT BY, although it may imply an intention to sort data, does not exist as a standard SQL function in the context of relevance scoring. Therefore, SCORE() is the appropriate choice for sorting fuzzy text search results by their relevance.
