It is a section on "search_high", while your question in your
previous mail was on "eff_pmtu":

Note that rest of your mail also contains a lot of
misunderstandings on the RFC. But, as you don't read
the RFC, collecting them is a waste of time.

Read the RFC thoroughly again and again, 10 times a day
for 30 days. Then, I may reply your further questions if
asked off list.

PERIOD.
