Search Logs functionality improvements

Feature

Ways I believe the search logs page could be improved:

  1. Display how many total searches took place in the time period selected
  2. Display what the overall and line-by-line click through percentage was
  3. Change “Unique” to “Unique Users”
  4. Enable filtering: by term, by # of searches, by clickthrough rate, by # of unique users

  1. Enable sorting by clicking on the column headers
  2. Provide export of the table to csv or similar
