Logical OR for two different fields in $where queries in mongodb

mongodb

Solution

Try this:

db.hotels.find({
    $where: "/london/i.test(this.city) || /hilton/i.test(this.hotel)"
})

NOTE As far as I understand `$where` does a per-document evaluation, so it can be pretty slow. If you'd have a single attribute, I'd suggested smth like

db.hotels.find({name: /(hilton|london)/i})

Problem

How do you do a query like the one below, where I want hotels in London OR hotels which have hilton in their name? This query db.hotels.find({$where : "name = /hilton/i || city = /london/i"}) gives such an error error: { "$err" : "$where compile error" } Both queries separately work ok: db.hotels.find({$where : "city = /london/i"}) db.hotels.find({$where : "name = /hilton/i"})
