  complete content of all man pages. It uses the FTS engine of SQLite to perform
  the search. The database is created with the help of the
  makemandb(8) utility.

    is more sophisticated than the classical version. Like modern search
    applications, it uses advanced techniques like stemming and term weighting
    to rank the matching results in decreasing order of relevance.
Quotes are optional for specifying multiword queries.
