# An instance of this class is returned by Rush::Commands#search. It contains
# both the list of entries which matched the search, as well as the raw line
# matches. These methods get equivalent functionality to "grep -l" and "grep -h".
#
# SearchResults mixes in Rush::Commands so that you can chain multiple searches
# or do file operations on the resulting entries.
#
# Examples:
#
# myproj['**/*.rb'].search(/class/).entries.size
# myproj['**/*.rb'].search(/class/).lines.size
# myproj['**/*.rb'].search(/class/).copy_to other_dir

# order it was received.
