Normally we can pass parameter to saved search by args.* form, but how to pass parameter not starting with args. such as $host$. In spl, savedsearch can pass parameter correctly, but if I invoke saved search dispatch action by rest api, parameter not starting with args can't be accepted, it will return an error.
Sample saved search query with host as one of the parameters that I want to substitute at runtime:
index=fooindex sourcetype=foosourcetype host=$args.host$
Sample JS code to dispatch with argument substitution:
mySavedSearch.dispatch({"args.host": "foohost"}, function(err, job) {
