>How do you save the data in the database - is it always the same single quote character or can be anything from these three types?

It could be any combination at the save an any combination at the search.

>Assuming you always convert bad quotes to a single quote when saving data, then you just need to adjust your search expression to replace different kind of quote with a single quote.

There are many sources of incoming saves. So, we have to consider the fact that there could be several types of quotes.

Yes, this is what I needed. I didn't think about that. But, this gives me an impression that I could lift any field in my data dictionary to identify a table field with its relational table field for the search usability. Then, if I set the property to True, when doing the search, that could be used.
