Simple mongodb search with meteor by using regular expressions. It tries to match all provided fields with the provided keywords. Inspired from http://www.stephentcannon.com/2013/11/meteor-alternative-to-mongodb-full-text.html

RegExp.quote = (str) ->
	(str + "").replace /([.?*+^$[\]\\(){}|-])/g, "\\$1"

Meteor.Collection::search = (options, cb) ->
	if options?.keywords?.length >= 3 and _.isString(options.keywords) and options.fields.length >= 1
		query = 
			'$or': []

		keywords = options.keywords.split " "

		_.each keywords, (keyword) ->
			if keyword
				_.each options.fields, (field) ->
					search = {}
					search[field] = new RegExp RegExp.quote(keyword), "i"
					query['$or'].push search

		cb(@find query)
	else
		cb null
