Bloomberg Security Lookup Request

Question

In the Bloomberg API Developer’s Guide it reads:

The Security Lookup [...] request constructs a search based upon the "query" element's string value, as well as the additional filters that you set [...]. This unctionality can also be found on the Bloomberg Professional service using the SECF < GO > function.

This is a simple snippet querying for IBM (C++, while I am actually targeting Java):

Service secfService = session.getService("//blp/instruments");
Request request = secfService.createRequest("instrumentListRequest");
request.asElement().setElement("query", "IBM");
request.asElement().setElement("yellowKeyFilter", "YK_FILTER_CORP");
request.asElement().setElement("languageOverride", "LANG_OVERRIDE_NONE");
request.asElement().setElement("maxResults", 10);
sendRequest(request, session);

With the SECF function I can set many other filters, such as the exchange, the country of domicile (which are also mapped in the FLDS function screen).

When I pass ("exchCode", "US"), I get an error.

com.bloomberglp.blpapi.NotFoundException: Element: exchCode not found in: InstrumentListRequest

(I tried with EXCH_CODE too)

How can I pass SECF filters to the request object?

Here's a snippet of Python code that dumps the schema for the InstrumentListRequest. Might be some language translation differences, but it's the same underlying API.
Sadly it doesn't look like you can formulate the query in the way you want to.
