/* Search Suggestion */

/*
Optimization Note:

These rules are currently implemented to minimize the number of suggestion requests:

    * No request is made for events that doesn't change the query (e.g. enter, arrow keys, etc.)
    * No request is made if the new characters added to the query wouldn't change the suggestion results.  That is,
      if the new query still forms a valid prefix of all the current suggestion results.
    * No request is made when the query is less than two characters.
    * If a query returns no result, additional characters appended to that query will not generate a request.
    * A request is made only after user pauses typing for some number of milliseconds.
