      Range check for DCG position discount lookup (#4069) · 4580393f
      ashok-ponnuswami-msft authored
      * Add check to prevent out of index lookup in the position discount table. Add debug logging to report number of queries found in the data.
      
      * Change debug logging location so that we can print the data file name as well.
      
      * Revert "Change debug logging location so that we can print the data file name as well."
      
      This reverts commit 3981b34bd6e0530f89c4733e78e6b6603bf50d48.
      
      * Add data file name to debug logging.
      
      * Move log line to a place where it is output even when query IDs are read from a separate file.
      
      * Also add the out-of-range check to rank metrics.
      
      * Perform check after number of queries is initialized.
      
      * Update
