Steps to reproduce:

Hi all,

I'm trying to do a search of hostgroups by name using the API. I've not having any luck as the API seems to return all hostgroups. the JSON request I'm generating looks like this

{'jsonrpc': '2.0', 'method': 'hostgroup.get', 'params': {'output': ['groupids', 'name'], 'search': {'name': '*Istanbul'}, 'excludeSearch': 'flase', 'searchWildcardsEnabled': 'true'}, 'id': 11, 'auth': 'xxx'}

I find this case ,but it is not resloved https://support.zabbix.com/browse/ZBX-4392
Any ideas, or an example?
