Question

我正在使用弹性搜索2.2.0，我是新手。我想使用两个过滤器搜索结果，但它显示了致命错误：查询不支持多个字段。

两个过滤器是：

plocation: china
pcategoryid: 0,20,21

这是我的代码：

$search = 'Doors';
$limit = 6;
$params = [
    'index' => 'product',
    'body' => [
        'query' => [
            "bool" => [
                "should" => [
                    'multi_match' => [
                        "fields" => [
                            "pname",
                            "pmodel",
                            "pcategoryname",
                            "pmetakeyword"
                        ],
                        "query" => $search,
                        "type" => "phrase",
                        "boost" => 10
                    ],
                    'multi_match' => [
                        "fields" => [
                            "pname",
                            "pmodel",
                            "pcategoryname",
                            "pmetakeyword"
                        ],
                        "query" => $search,
                        "type" => "most_fields",
                        "fuzziness" => "1",
                        "boost" => 0
                    ]
                ]
            ],
        ],

        "filter" => [
            "bool" => [
                "must" => [
                    "term" => [
                        "ptypeid" => 1
                    ]
                ],
                "should" => [
                    "term" => [
                        "psearchstatus" => 1
                    ]
                ],
                "filter" => [
                    "terms" => [
                        "plocation" => ['china'], "pcategoryid" => [0,20,21]
                    ]
                ]
            ],
        ],
        "from" => ($page - 1) * $limit,
        "size" => $limit
    ],
];
$client = Elasticsearch\ClientBuilder::create()->build();
$response = $client->search($params);
$results = $response['hits']['hits'];

还有另一种方法可以解决我正在尝试做什么，或者我是否在正确的轨道上？

Answer 1

问题是您尝试申请的terms filter。与上面的term过滤器一样，它只接受一个字段，但带有一组值。

"terms" => [
  "plocation" => ['china'], "pcategoryid" => [0,20,21]
]

应该是

"terms" => [
  "plocation" => ['china']
],
"terms" => [
  "pcategoryid" => [0,20,21]
]

多项术语过滤器不适用于弹性搜索
