  - getCollation
```
public CollationOptions getCollation()
```
  - setCollation
```
public IndexOptions setCollation(CollationOptions collation)
```
    Optional. Specifies the collation for the index.
    Collation allows users to specify language-specific rules for string comparison, such as rules for lettercase and accent marks.
    If you have specified a collation at the collection level, then: If you do not specify a collation when creating the index, MongoDB creates the index with the collection's default collation. If you do specify a collation when creating the index, MongoDB creates the index with the specified collation. When specifying collation, the locale field is mandatory; all other collation fields are optional. For descriptions of the fields, see Collation Document.
