[scripted field] convert String date to timestamp

(HJ Shin) #1


I am trying to calculate dates in scripted field.

If I want to calculated between elasticsearch field and date string, what should I do?

I think I need to convert string type date to timestamp.
What is the way to do that?

if('2017-01-01'-doc['WK_DT'].value > 0){
return '2017-01-01'-doc['WK_DT'].value
return '-1'

How do I subtract two timestamps in VisualBuilder
