Freetext search on product data yields unexpected results with unicode characters

[AndreasKl]

If a ProductProjectionSearch#withText for a german umlaut is executed the search does not include words with the umlaut in the result set.

This ticket is mostly for tracking purposes as this could be a backend issue.

I could reproduce and tried to make a workaround:

Copy this class in the right package in your codebase https://gist.github.com/schleichardt/d8b3a9e1f82776fa7403

Usage:

final SearchDsl<ProductProjection> underlying = 
    ProductProjectionSearch.of(ProductProjectionType.STAGED).withText(GERMAN, "öón");
final Search<ProductProjection> useThisForExecute = Bug240Workaround.of(underlying);

Sorry, it is a bug inherited from the Play SDK.
