But your index currently has unnormalized values.
Thus, you must rebuild it.

When you rebuild it, you can also give it a different name.

Yes, replace it by "NormalizedSearchableText".

You can (and must) normalized the search terms.
However, the indexed values need be normalized, too.

Almost surely, there are not now. This means, rebuilding the
index -- this time with normalization...
