title: How to improve search results with QueryElevationComponent?
body: <p>I'm using solr 1.4 and using QueryElevation Component for guaranteed search position. I have around 700,000 documents with 1 Mb elevation file. It turns out it is quite slow on the newrelic monitoring website:</p>

  <p>I'm looking for how to improve the speed of the search query. The
  QueryElevation Component is taking too much time which is
  unacceptable. The size of elevation file is only 1 Mb. I wonder other
  people using this component without problems (related to speed)? Am I
  using it the wrong way or there is a limit when using this component?</p>
