Indexable expressions can include functions, operators, and conditions that can be evaluated using indexes, reducing the need for a full table scan. By using indexable expressions, developers and database administrators can significantly improve query performance, especially on large datasets. The ability of an expression to be indexable depends on several factors, including the structure of the index, the data type, and how the query is formulated.
