Handling a case of searching an empty database

Hi, I have posted a question on Stack Overflow but there is limited support for ObjectDB on there, so I will post it here. It is a lot clearer on the page, if this is a problem though I can copy it to a post here.

Thanks in advance.

Answer was added in StackOverflow.

All working now, thank you very much :D
