In the future, there should be a local documentation search driven
by AI algorithms which handles synonyms and rewordings, so that if
the user searched for "dereference", they also found text about
"following a reference" even if the word "dereference" wasn't used.
Think of it like a version of G**gle running on your own machine.
Implementing such a thing is beyond me, though.
