while I was mucking with term enumeration i found that

For my purposes to skip around i simply close the term enum and get a
new one from the indexReader at a different starting point.
Not that I want to touch it, just mentioning i thought it was a
little non-obvious that skipTo() is so inefficient, it keeps
enumerating until compareTo() returns what it wants...

Indeed - somewhat related:
https://issues.apache.org/jira/browse/LUCENE-1592
I've changed
"Some implementations are considerably more efficient than that."
to
"Some implementations *could* be considerably more efficient than a
linear scan.
Check the implementation to be sure."
