/*

The websites that have some MRI detected AND which are either in NZ or with NZ TLD
or (so if they're from overseas) don't contain /mi or mi.* in URL path.
We'll include Australia, to get the valid "kiwiproperty.com" website,
otherwise the sole exception, included in the result list.


db.getCollection('Websites').find({$and: [
                {numPagesContainingMRI: {$gt: 0}},
                {$or: [{geoLocationCountryCode: /(NZ|AU)/}, {domain: /\.nz$/}, {urlContainsLangCodeInPath: false}]}
            ]}).count()

397

Aggregate results by a count of country codes:

db.Websites.aggregate([
    {
        $match: {
            $and: [
                {numPagesContainingMRI: {$gt: 0}},
                {$or: [{geoLocationCountryCode: /(NZ|AU)/}, {domain: /\.nz$/}, {urlContainsLangCodeInPath: false}]}
            ]
        }
    },
    { $unwind: "$geoLocationCountryCode" },
    {
        $group: {
            _id: {$toLower: '$geoLocationCountryCode'},
            count: { $sum: 1 }
        }
    },
    { $sort : { count : -1} }
]);
