 * [FILTER_COMPARISON_RULE]
 * `lt`|`lte`|`gt`|`gte`:
 * + rval must be a number. And lval will be converted to number (`numericToNumber`) to compare.
 * `eq`:
 * + If same type, compare with `===`.
 * + If there is one number, convert to number (`numericToNumber`) to compare.
 * + Else return `false`.
 * `ne`:
 * + Not `eq`.
 *
 *
 * [SORT_COMPARISON_RULE]
 * All the values are grouped into three categories:
 * + "numeric" (number and numeric string)
 * + "non-numeric-string" (string that excluding numeric string)
 * + "others"
 * "numeric" vs "numeric": values are ordered by number order.
 * "non-numeric-string" vs "non-numeric-string": values are ordered by ES spec (#sec-abstract-relational-comparison).
 * "others" vs "others": do not change order (always return 0).
 * "numeric" vs "non-numeric-string": "non-numeric-string" is treated as "incomparable".
 * "number" vs "others": "others" is treated as "incomparable".
 * "non-numeric-string" vs "others": "others" is treated as "incomparable".
 * "incomparable" will be seen as -Infinity or Infinity (depends on the settings).
 * MEMO:
 *   Non-numeric string sort makes sense when we need to put the items with the same tag together.
 *   But if we support string sort, we still need to avoid the misleading like `'2' > '12'`,
 *   So we treat "numeric-string" sorted by number order rather than string comparison.
 *
 *
 * [CHECK_LIST_OF_THE_RULE_DESIGN]
 * + Do not support string comparison until required. And also need to
 *   avoid the misleading of "2" > "12".
 * + Should avoid the misleading case:
 *   `" 22 " gte "22"` is `true` but `" 22 " eq "22"` is `false`.
 * + JS bad case should be avoided: null <= 0, [] <= 0, ' ' <= 0, ...
 * + Only "numeric" can be converted to comparable number, otherwise converted to NaN.
 *   See `util/number.ts#numericToNumber`.
 *
