I did what you said, but it still isn't working properly. The dropdowns are now working again, which is an improvement, but host_src seems to only contain the host values. When I open the query in search, it only searches for the hosts and the text in the textbox, leaving out the source.
In addition, I am looking for events with host = $host$ source = $src$ $srch$, not just $host$ $src$ $srch$. How can I do this?
For reference, my csv file looks like this:
application,environment,hostCode,sourceCode
applicationA,DEV,awslxappA-d*,appA
applicationA,PROD,awslxappA-p*,appA
applicationA,QA,awslxappA-q*,appA
applicationB,DEV,awslxappB-d*,appB
applicationC1,DEV,awslxappC-d*,appC1
applicationC1,PROD,awslxappC-p*,appC1
applicationC1,QA,awslxappC-q*,appC1
applicationC2,DEV,awslxappC-d*,appC2
applicationC2,PROD,awslxappC-p*,appC2
applicationC2,QA,awslxappC-q*,appC1
