So in short. When you index a field with a text type and default analyzer, it is indexed in lowercase and broken into tokens.

`Aaa Bbb` became `aaa`, `bbb`.

When you search with a wildcard query (which is a bad idea), you must use the same case as was indexed. So `aa*` should work where `Aa*` shouldn't.

For keywords, they are indexed as `Aaa Bbb`, so searching for `Aa*` will match. Note that `Bb*` won't match.

With a lowercase normalizer, `aa*` will match. `Aa*`, `Bb*` or `bb*` won't match.
