Simple cloudant word search by timestamp - need help

My cloudant database was created with the following: msg.payload via tweetnode to cloudant

{ 
   "timestamp" : msg.tweet.timestamp_ms, 
   "tweet" : msg.tweet.text, 
   "sentiment" : msg.sentiment.score
}

I would like to search the tweet field by word and timestamp by a range of dates. Then save the results by tagging the tweets found back to cloudant via node-red.

This seems like a routine thing people do. I have not found any flows that do this. Help is appreciated - especially a link to a working search by text using cloudant flow!

The index I am using is this

function(doc) {
index("default", doc._id);
if (doc.timestamp) {
index("timestamp", doc.timestamp, {"store": true});
}
if (doc.tweet) {
index("tweet", doc.tweet, {"store": true});
}
if (doc.sentiment) {
index("sentiment", doc.sentiment, {"store": true});
}
}

Here is the very simple flow :
I need the correct .json to access searching by text
