+ * Compares two index specifications to determine if they are equal.
+ *
+ * #### Example:
+ *     isIndexSpecEqual({ a: 1, b: 1 }, { a: 1, b: 1 }); // true
+ *     isIndexSpecEqual({ a: 1, b: 1 }, { b: 1, a: 1 }); // false
+ *     isIndexSpecEqual({ a: 1, b: -1 }, { a: 1, b: 1 }); // false
+ *
+ * @param {Object} spec1 The first index specification to compare.
+ * @param {Object} spec2 The second index specification to compare.
+ * @returns {Boolean} Returns true if the index specifications are equal, otherwise returns false.
