Breaking changes of ES 1.7.2 with kibana3

hi ,
we have upgraded out elasticsearch cluster version 0.90.10 to 1.7.2 .
out kibana3 broke with messages as the following when we try to search on some field in the index:
Oops! SearchParseException[[webnode_2015-11-25][0]: from[-1],size[-1]: Parse Failure [Failed to parse source [{"facets":{"4":{"date_histogram":{"field":"date","interval":"30s"},"facet_filter":{"fquery":{"query":{"filtered":{"query":{"query_string":{"query":"ScanTime: [1000 TO *]"}},"filter":{"bool":{"must":[{"match_all":{}},{"fquery":{"query":{"field":{"myfield":{"query":"(\"ssl-images-blavbla.com\")"}}},"_cache":true}},{"range":{"date":{"from":1448437723039,"to":"now"}}},{"fquery":{"query":{"field":{"myfield":{"query":"(\"ssl-images-blavbla.com\")"}}},"_cache":true}},{"bool":{"must":[{"match_all":{}}]}}]}}}}}}}},"size":0}]]]
i saw this link breaking changes
but i couldn't change my kibana's json configuration to fit the 1.7.2 ES .
what value in the json exactly should change to what?
