[tdwg-tag] Making a query from a external application to Tapir client

Hello, I'm developing a program to make searches to the Tapir client. To do that, I have to include the parameteres of the query in the URL using the GET method. I have studied the source code and I think I should include the parameter "request" with the encoded query but it doesn't work for me. How the URL can be formed? What parameters do I have to include? Thanks in advance! Best, Daniel
