What is the best way to document complex / dynamic objects as arguments to a function?

ex.js

/**
 * Below are several examples of methods that are difficult to clearly annotate with JSDoc annotations.
 */

/**
 * @param {Object} people An index of people keyed by a person's name
 * @returns {Object} map An index of zipcodes keyed by a person's name
 */
 
function find(people) {
  return Object.keys(people).reduce({}, function(prev, cur) {
    prev[cur] = zipFor(cur);
    return prev;
  });
}

/**
 * @param {Object} options The options to set
 */
 
function configure(options) {
 this.options = options;
}

/**
 * @param {Object} options The options to set
 */
 
function configure(options) {
 this.options = options;
}


/**
 * @param {Object} options The options to set
 * @param {Object} options.server The server options
 * @param {String} options.server.host The server host
 * @param {String|Number} options.server.port The server port
 * @param {Array} options.remoteHosts An array of server options
 */
 
function betterConfigure(options) {
 this.options = options;
}



/**
 * The issue:
 * 
 *  - the documentation above is not clear and sometimes incomplete
 *  - an example would help, but would not be explicit
 *  - it is difficult to describe objects within arrays
 */
