silent_fail_session_proxy.rb

#
# Silently fail instead of raising an exception when an error occurs while writing to Solr.
# NOTE: does not fail for reads; you should catch those exceptions, for example in a rescue_from statement.
#
# To configure, add this to an initializer:
#    Sunspot.session = SilentFailSessionProxy.new
#
# This is for Sunspot 0.18 and would need to be changed a little bit for Sunspot 1.0.
