I am a beginner and working on elasticsearch php for a simple search. I have to set filters conditionally based on weather the filter is selected or not. Hence I have made the filters for that specific task and placed them in different files. All i do is include these files when the isset returns true. But the trouble is, if more than one filter is selected, then the last filter overwrites the filter part of array and does not provide the required multiple filtered answer. Is there anyway to make this work? (Please pardon me if it is inefficient as I am a beginner and just trying to learn.)

我是初学者，正在使用elasticsearch php进行简单的搜索。我必须根据天气选择或不选择过滤器来有条件地设置过滤器。因此，我为该特定任务制作了过滤器，并将它们放在不同的文件中。我所做的就是当isset返回true时包含这些文件。但问题是，如果选择了多个过滤器，则最后一个过滤器会覆盖数组的过滤器部分，并且不会提供所需的多个过滤答案。反正有没有让这项工作？ （请原谅我，因为我是初学者，只是想学习，效率低下。）

My files are something like this

我的文件是这样的

BalFilter.php

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

AgeFilter.php

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

OnlyQuery.php

OnlyQuery.php

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

And in the main index

并在主要指数

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";
}

...
include "OnlyQuery.php";

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

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

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);
}
