"User Guide" :-)

It is the very first line of the manual.

The debbugs manual itself is intended for the SOAP backend, if somebody
wants to write another interface but debbugs-gnu.el and debbugs-org.el.

Well, personally I haven't used regular expressions yet. The don't work
for me either.

For simple tests, you might use <>.
debbugs-gnu-search shall be have similar.

In your case, knowing the the Estraier search machine is not really full
text based but word based, I would try

(debbugs-gnu-search "el AND search AND sources" nil nil nil nil)

This gives you 120 hits. Likely some of them are false postives, but it
shall be manageable.

Btw, maybe I shall make all debbugs-gnu-search arguments optional ...
