Hi,
Let me explain you *time* *parameters in Solr*:
*Timing* parameter of debug returns information about how long the query
took to process.
*Query time* shows information of how long did it take in Solr to get the
search
results. It doesn't include reading bits from disk, etc.
Also, there is another parameter named as *elapsed time*. It shows time
frame of the query sent to Solr and response is returned. Includes query
time, reading bits from disk, constructing the response and transmissioning
it, etc.
Kind Regards,
Furkan KAMACI
