# CaseNormalization

The case conversion to use for all incoming text. To improve performance, use this parameter to convert all text to lowercase or uppercase before attempting to match text.

This parameter takes one of the following values:

- None. No case conversion.
- Lower. All incoming text is converted to lowercase.
- Upper. All incoming text is converted to uppercase.

If your grammar file consists of only lowercase or only uppercase characters but your text is mixed case, you can improve performance by setting `CaseNormalization` to `Lower` or `Upper` respectively. This provides a greater performance improvement than setting `MatchCase` to `False`.

If you set this parameter to `Lower` or `Upper`, set `MatchCase` to `True`.

NOTE: When using the Eduction Server Linguistic Sentiment Analysis grammar, Micro Focus recommends that you set this parameter to `Lower` and the `MatchCase` parameter to `True` to ensure optimal performance.
