[Koha] Z39.50 Search

[Vitor Fernandes]

Hi there Koha community,

I've one question about Z39.50, which is not directly related with Koha.
If I search in Koha for titles with "a" in the Z39.50 search, what is returned?

Records with the word "a" in the title?
Records with the letter "a" in the title or words started by "a"?

This question it's because I need to do a query to one Z39.50 server
that returns me the records with at least one word started with "a".
If someone can help me, i would be appreciated.

Thanks in advance.
