How to create a watcher script to match one field with other field in same document

Hi ,

Can anyone please help me on this scenario to create an alert
I am having a log events like the following

<#> 20200806 17:04:23.261 280018000 EV.WRN [ MVINB-LSL2.T1G1_WEBSVR1 main.main TSP1.T1G1_WEBSVR1 ] Failed to load TermRecord for TermID=f6y4jkm

<#> 20200806 17:04:23.261 280018000 EV.WRN [ MVINB-LSL2.T1G1_WEBSVR1 main.main TSP1.T1G1_WEBSVR1 ] Failed to load TermRecord for TermID=f6y4jkm

<#> 20200806 17:04:23.261 280018000 EV.INF [ MVINB-LSL2.T1G1_WEBSVR1 main.main TSP1.T1G1_WEBSVR1 ] Failed to load TermRecord for TermID=7yhe73v

<#> 20200806 17:04:23.261 280018000 EV.FNE [ MVINB-LSL2.T1G1_WEBSVR1 main.main TSP1.T1G1_WEBSVR1 ] Failed to load TermRecord for TermID=j6ljudn

here EV.WRN is the "event_type" and "Failed to load TermRecord for TermID=f6y4jkm" is the log_message.

i want to create an alert if get the the same "event_type" with the same "log_message"
with the same term id. Is there a way to generate and alert based upon this scenario. the following is my current watcher script.
