RethinkDB Query: How to pluck bassed on a date range - rethinkdb

Question

Given a table called alerts and a database called database with an array
of objects with a date attribute called History how can I pluck based
on a date range on that date attribute?
with the following query,
r.db("database").table("alerts").pluck("history").limit(10000)
I get back something like the following
{
"history": [
{
"text": "text1" ,
"updateTime": Thu Jun 20 2019 01:29:47 GMT+00:00 ,
},
{
"text": "text2" ,
"updateTime": Thu Jun 20 2019 01:24:59 GMT+00:00 ,
},
]
}
{
"history": [
{
"text": "text3" ,
"updateTime": Thu Jun 20 2018 01:29:47 GMT+00:00 ,
},
{
"text": "text4" ,
"updateTime": Thu Jun 20 2018 01:24:59 GMT+00:00 ,
},
]
}
how can I pluck the sub object called history and only return histories that are in a specific range on the updateTime attribute.
for example between jan/2/2009 to jan/3/2009

You need to filter based on a time range and use pluck on a nested object. Here are some examples about how to do that from the official documentation
r.table("users").filter(function (user) {
return user("subscriptionDate").during(
r.time(2012, 1, 1, 'Z'), r.time(2013, 1, 1, 'Z'));
}).run(conn, callback);

r.table('marvel').pluck({'abilities' : {'damage' : true, 'mana_cost' : true}, 'weapons' : true}).run(conn, callback)
