Both ReconnectedTime and ReconnectedDetails are multivalue fields. In each event the "ReconnectedTime" value [ substring which needs to be valuated ] exists in "ReconnectedDetails" then only the matched substring values of ReconnectedDetails should be the final Ouput.

hi @vn_g ,

Try this:

 

<your_base_search>
| eval ReconnectedTime_orig=ReconnectedTime 
| nomv ReconnectedTime_orig
| mvexpand ReconnectedTime 
| mvexpand ReconnectedDetails 
| where match(ReconnectedDetails, ReconnectedTime) 
| stats values(ReconnectedTime) as ReconnectedTime values(ReconnectedDetails) as ReconnectedDetails by ReconnectedTime_orig 
| fields ReconnectedTime, ReconnectedDetails

No the output is not as expected. All 3 values of "Reconnected Details" are being displayed for each "ReconnectedTime". Only the sub string value of ReconnectedTime in Reconnected Details should be displayed for Reconnected Details.
