+       |
+       | **Data Type**: {+string-data-type+}
+
+   * - ``caseLevel``
+     - | *(Optional)* Specifies whether to include case comparison.
+       |
+       | When set to ``true``, the comparison behavior depends on the value of
+         the ``strength`` field:
+       |
+       | - If ``strength`` is ``1``, the {+library-short+} compares base
+       |   characters and case.
+       |
+       | - If ``strength`` is ``2``, the {+library-short+} compares base
+       |   characters, diacritics, other secondary differences, and case.
+       |
+       | - If ``strength`` is any other value, this field is ignored.
+       |
+       | When set to ``false``, the {+library-short+} doesn't include case comparison at
+         strength level ``1`` or ``2``.
+       |
+       | **Data Type**: {+bool-data-type+} 
+       | **Default**: ``false``
+
+   * - ``caseFirst``
+     - | *(Optional)* Specifies the sort order of case differences during tertiary
+         level comparisons.
+       |
+       | **Data Type**: {+string-data-type+} 
+       | **Default**: ``"off"``
+
+   * - ``strength``
+     - | *(Optional)* Specifies the level of comparison to perform, as defined in the
+         `ICU documentation <https://unicode-org.github.io/icu/userguide/collation/concepts.html#comparison-levels>`__.
+       |
+       | **Data Type**: {+int-data-type+} 
+       | **Default**: ``3``
+
+   * - ``numericOrdering``
+     - | *(Optional)* Specifies whether the driver compares numeric strings as numbers.
+       | 
+       | If set to ``true``, the {+library-short+} compares numeric strings as numbers.
+         For example, when comparing the strings "10" and "2", the library uses the
+         strings' numeric values and treats "10" as greater than "2".
+       |  
+       | If set to ``false``, the {+library-short+} compares numeric strings
+         as strings. For example, when comparing the strings "10" and "2", the library
+         compares one character at a time and treats "10" as less than "2".

+       | **Data Type**: {+bool-data-type+}
+       | **Default**: ``false``
+
+   * - ``alternate``
+     - | *(Optional)* Specifies whether the library considers whitespace and punctuation as base
+         characters for comparison purposes.
+       |
+       | **Data Type**: {+string-data-type+}
+       | **Default**: ``"non-ignorable"``
+
+   * - ``maxVariable``
+     - | *(Optional)* Specifies which characters the library considers ignorable when
+         the ``alternate`` field is set to ``"shifted"``.
+       |
+       | **Data Type**: {+string-data-type+}
+       | **Default**: ``"punct"``
+
+   * - ``backwards``
+     - | *(Optional)* Specifies whether strings containing diacritics sort from the back of the string
+         to the front.
+       |
+       | **Data Type**: {+bool-data-type+} 
+       | **Default**: ``false``
