php - 将多个过滤器添加到ElasticsearchPhp中的现有过滤器

Question

我是初学者，正在研究Elasticsearch php，以进行简单的搜索。
我必须根据天气情况有条件地设置过滤器，无论是否选择过滤器。
因此，我为该特定任务创建了过滤器，并将其放置在不同的文件中。我要做的就是在isset返回true时包括这些文件。
但是麻烦在于，如果选择了多个过滤器，那么最后一个过滤器将覆盖数组的过滤器部分，并且无法提供所需的多个过滤后的答案。反正有做这项工作吗？
(如果我是初学者，只是想学习，如果效率低下，请原谅我。)

我的文件是这样的

BalFilter.php

<?php

if ($val == 1) {
    $params['body']['query']['filtered']['filter'] = ['range' => [
            'balance' => ['gte' => $bal]
        ]
    ];
}
if ($val == 2) {
    $params['body']['query']['filtered']['filter'] = ['range' => [
            'balance' => ['lte' => $bal]
        ]
    ];
}

AgeFilter.php

<?php
$params['body']['query']['filtered']['filter']['term'] = ['age' => $age];

OnlyQuery.php

<?php 
$params['body']['query']['filtered']['query'] = [ 'query_string' => [
                                                  'default_field' => '_all',
                                                  'query' => $q,
                                                  'lenient' => true
                                                                ]
                                               ];

而在主要指标

if (isset($_GET['age'])) {
    $age = $_GET['age'];
} else {
    $age = 0;
}
if (isset($_GET['val'])) {
    $val = $_GET['val'];
} else {
    $val = 0;
}
if (isset($_GET['bal'])) {
    $bal = $_GET['bal'];
} else {
    $bal = 0;
}

include "OnlyQuery.php";

if ($age != 0) {
    include "AgeFilter.php";
}
if (($val == 0 && $bal != 0) || ($val != 0 && $bal == 0)) {
    echo "Please choose the right combination for balance";
}
if ($val != 0 && $bal != 0) {
    include "BalFilter.php";
}

Answer 1

您可以做的是创建一个bool/must过滤器数组，该数组将由包含文件中的每个过滤器填充。可以使用OnlyQuery.php或在添加OnlyQuery.php之后完成，基本上是这样的:

...
include "OnlyQuery.php";

$params['body']['query']['filtered']['filter'] = array('bool' => [
    'must' => []
]);
...

然后可以将 AgeFilter.php更改为此:

$term = array('term' => ['age' => $age]);
array_push($params['body']['query']['filtered']['filter']['bool']['must'], $term);

和 BalFilter.php到这

if ($val == 1) {
    $range = array('range' => [
        'balance' => ['gte' => $bal]
    ]);
    array_push($params['body']['query']['filtered']['filter']['bool']['must'], $range);
}
if ($val == 2) {
    $range = array('range' => [
        'balance' => ['lte' => $bal]
    ]);
    array_push($params['body']['query']['filtered']['filter']['bool']['must'], $range);
}
