However I get the full array, as if no filtering was done !\nBut if I filter on only one element, for example:\n\n``` javascript\nvar expression = { answerer : { email: 'adm' } };\n```\n\nIt works as expected and returns only the second element of array.\n\nI also tried to define differently my filter expression:\n\n``` javascript\nvar expression = { 'answerer.email': 'adm' } };\n```\n\nBut this returns no result at all.\n\nSo it would seem there is a bug when filtering on more than one nested property.\n\nA workaround could be to use a custom comparator functions. Any other ideas (besides flattening my array...) ?\n","author":{"url":"https://github.com/barroudjo","@type":"Person","name":"barroudjo"},"datePublished":"2014-10-20T16:05:55.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/9698/angular.js/issues/9698"}
