Usage

1. Add 'SEARCHABLE' attribute to your encrypted fields annotations.
   

// make the encrypted 'messages' field in Collection 'Messages' searchable
Messages._encrypted_fields({'message': {princ: 'roomprinc', 
                                           princtype: 'room', 
                                           auth: ['_id', 'foo'],
                                           attr: 'SEARCHABLE'}});

2. Publish a search filter on the server ```javascript // publishes filter for "Messages" Collection named "messages-user-can-access" // takes in an argument "userID" to identify the rooms user has access to // returns an array of room ID's to check against each message Messages.publish_search_filter("messages-user-can-access", function (userID) { // create a list of all the rooms this user has access to var rooms = Rooms.find({$or: [{createdByID: userID}, {invitedID : userID}]}).fetch(); var filters = []; _.each(rooms, function(room) { filters.push({rID: room._id}); });

return filters;
};

});

3. Search for words in fields of a collection using a filter
```javascript
// search for word 'foo' in field 'message' using filter 'blue-colored'
// use logged in user's principal & pass in 'filterInput' to search filter
// log search result in callback
Messages.search("blue-colored", {'message': 'foo'}, Principal.user(), 'filterInput', function (result) {console.log("Search result: " + result);});
