# ThinkingSphinx lazily executes search requests. 
# This means that search results aren't usually 
# loaded until you iterate over the results in the view.
# This can sometimes make tracking down performance 
# problems a little tricky, as new relic will report all 
# your time spent rendering such and such partial or view.
# Adding this file to your rails app will make the 
# time spent in sphinx properly report itself
