Question

我正在尝试使用PHP客户端在索引之前检查用户的输入是否已存在。

我已阅读过一些类似的帖子（例如Check Elasticsearch document similarity before indexing或Check if the index exists or not Elasticsearch），但它们并没有涵盖如何实现这一目标。

我尝试使用$client->search和$client->index，但我在$client->search行上收到以下错误：

HP致命错误：未捕获Elasticsearch \ Common \ Exceptions \ ServerErrorResponseException：{“error”：{“root_cause”：[{“type”：“illegal_state_exception”，“reason”：“无法在START_ARRAY上获取文字1：129" }] ...

这是我尝试过的代码：

   <?php
   require_once 'app/init.php';


    if(!empty($_POST)) {
      //Determines if the variables are set
      if (isset($_POST['title'], $_POST['description'], $_POST['thema'], $_POST['type'])) {
        $title = $_POST['title'];
        $description = $_POST['description'];
        $thema = explode(',', $_POST['thema']);
        $type = $_POST['type'];

        $searched = $client->search([
          'index' => 'my_index',
          'type' => 'default',
          'body' => [
            'query' => [
              'bool' => [
                'should' => [
                  [ 'match_phrase' => [ 'Title' => $title ] ],
                  [ 'match_phrase' => [ 'Description' => $description ] ],
                  [ 'match_phrase' => [ 'Thema' => $thema ] ],
                  [ 'match_phrase' => [ 'Type' => $type ] ],
                ]
              ]
            ]
          ]
        ]);
        if($searched['hits']['total'] >= 1) { 
         print_r("Your idea already exists in the database");
        } 
       else {
        $indexed = $client->index([
          'index' => 'january-2018',
          'type' => 'default',
          'body' => [
            'Titel' => $titel,
            'Beschreibung' => $beschreibung,
            'Thema' => $thema,
            'Beitragstyp' => $beitragstyp
          ]
        ]);
       print_r("Your idea has been successfully submitted! The ID for your submission is: " . $indexed['_id']);        

      }
    }

    ?>
