Hello,
I am using Dspace 4.0.
I notice that when i search a query like --test i get an internal error.
The same happens and in the online JSPUI Demo.
I tried a solution like this: i included the following code just before
<dspace sidebar>.
<% if (qResults != null) { %>
<dspace:sidebar>
........
........
</dspace:sidebar>
<% } %>
</dspace:layout>
and it seems to working fine. I get as a result the message key
"jsp.search.error.discovery".
I do not know if this is a possible solution but it's working.
The error stacktrace was:
An internal server error occurred on http://localhost:8080/jspui:
Date: 7/5/2014 12:22 μμ

-- Method: GET
-- Parameters were:

-- rpp: "10"
-- sort_by: "score"
-- location: "/"
-- query: "--test"
