现在，如果查询超过2个符号，ElasticSearch会给出结果。如何配置elasticsearch php，搜索在最小1个输入符号后工作？
这是一个例子：
{
"_index": "users",
"_type": "profiles",
"_id": "7",
"_version": 2,
"_score": 1,
"_source": {
"id": "544",
"type": "1",
"name": "Babaev",
"photo": "/06/07/07/38/145x145/667200b3d3beffd4178ccd05903544d8.jpg",
"country": "Mordoc",
"SpecializationName": null,
"rating": "0"
}
}
