How to set the timerange from 12:00 AM to 11:59 PM for search in watcher json file

[Mohanraj (Mohanraj Subburaj)]

I am trying to collect the count of a specific text from our indices for the past one day (12 am to 11:59 PM) and send the count details by email next day 6 am.
how to do specify the timerange in the search section. do we have any examples ?
for example, the below example will start the search from the current time and not from 12 am.
"range": {
"@timestamp": {
"from": "now-5m"
}

@Mohanraj,

You can use the /d operator to round down to the nearest day. To get all of yesterday, you could do something like this:

"range": { 
     "@timestamp" : { 
         "gte": "now-1d/d",
         "lt": "now/d"
    }
}
