Repair easy text search on test field

[openlowcode]

Text field on an object should have an easy search function. The function is part of the framework today, but not implemented.

The context is to take a text, remove all spaces, dots, commas..., keep only letters and numbers and put letters to upper case. This will be stored in a special field.

When doing a search, the text to search will be normalized the same way, and search will be done on the special field. So when searching for " Hello, World", "hello world" will also be returned.
