Hi Is it possible to use an indexed script in the condition field of a watch with the "compare" condition type?  
My indexed script does not return a boolean (true/false) but a value which I want to compare to another value in the watch condition.  
I know I could do this within the script, but I want to use this script for several watches and would rather not have individual scripts per watch. Please note I do not have inline scripting enabled and this is not an option for security purposes.

Thanks

Hey,

the compare condition has nothing to do with scripting - it was created to not have scripting enabled.

The script condition supports indexed scripts. If the value changes, you could access the `metadata` field in your script, which is configured when [creating a watch](https://www.elastic.co/guide/en/watcher/2.4/watch-definition.html).
