// SYNOPSIS
//
struct search_options
//
// DESCRIPTION
//
// A search_options is the set of command-line options to the "search"
// executable. These are all packaged into a structure because, in
// addition to parsing command-line options initially, "search," if run as
// a daemon, needs to parse "command-line" options per request via a
// socket. The options are therefore packaged together into an object so
// each thread can have its own set of options, i.e., be thread-safe.
//
// Structure member names are such that those that end in "_arg" are the
// value of the argument of the option (which implies that the option was
// given) and those that end in "_opt" are Boolean options and, if true,
// mean that the option was given.
//
