Nugget Post: Pouchdb-find regex example

Here’s an example of using the excellent pouchdb-find plugin’s (https://github.com/nolanlawson/pouchdb-find) regex features. I couldn’t really find a good example in the documentation, but looking at the source code we come up with something like this:

	db.find({
	selector: {
	_id: {$gte: null},
	name: {$regex: ".ri."}
	},
	fields: ['_id', 'debut', 'name', 'series']
	});

Note that the $regex command cannot be run on an indexed field, so this will be a slow query – apart from the expensive regex operation, all records are being loaded into memory and scanned.

The above example can be run on the pouchdb-find demo site (http://nolanlawson.github.io/pouchdb-find/)
