I am using the new Zoho Mail web interface and am trying to build a custom search query that returns all flagged emails sent to either one of three recipients (multiple OR condition). 

I though of something like To=( a@example.com, b@example.com, c@example.com) Is:Flagged, but there don't seem to be a place to actually put this query. 

I read the instructions on power search, but those seem to be targeting the old web interface. At least I haven't been able to achieve anything mentioned there. 

Therefore I would like to ask if the search feature of the new web interface can be used to build more complex custom queries. If so, could you give an example and show me where to enter the query?

If power search is not (yet) available with the new web interface, are there any other options do a custom search (and save it)?

Cheers,

Stefan
