class << self #class methods
# Searches for a ticket or group of tickets with an active record like interface.
#
# Find has 3 different ways to search for tickets
#
# * search for tickets by the id. This will search for the Ticket with the exact id and will automatically load the entire ticket into the object (full will return true).
# * search for all tickets with a hash for search options by specifying :all along with your options. This will return an array of tickets or an empty array if no tickets are found that match the options.
# * search for a single ticket with a hash for search options by specifying :first along with your options. This will return a single ticket object or nil if no tickets are found.
#
# A hash of options for search paramaters are passed in as the last argument.
#
# ====Parameters
# * :queue or :queues - the name of a queue in the ticket system. This can be specified as a string, a symbol or an array of strings or symbols. The array will search for tickets included in either queue.
# * :status - the status of the tickets to search for. This can be specified as a string, a symbol or an array of strings or symbols.
# * :subject, :content, content_type, file_name - takes a string and searches for that string in the respective field.
# * :created, :started, :resolved, :told, :last_updated, :starts, :due, :updated - looks for dates for the respective fields. Can take a Range, Array, String, Time. Range will find all tickets between the two dates (after the first, before the last). Array works the same way, using #first and #last on the array. The elements should be either db-time formatted strings or Time objects. Time will be formatted as a db string. String will be passed straight to the search.
# * :custom_fields - takes a hash of custom fields to search for. the key should be the name of the field exactly how it is in RT and the value will be what to search for.
#
# ==== Examples
#
# # find first
# MyTicket.find(:first)
# MyTicket.find(:first, :queue => 'My Queue')
# MyTicket.find(:first, :status => [:new, :open])
# MyTicket.find(:first, :queue => 'My Queue', :status => :resolved)
# MyTicket.find(:first, :custom_fields => {:phone => '8675309'})
#
# # find all
# MyTicket.find(:all, :subject => 'is down')
# MyTicket.find(:all, :created => [Time.now - 300, Time.now])
# MyTicket.find(:all, :queues => ['my queue', 'issues'])
#
# # find by id
# MyTicket.find(12345)
