使用 php curl 在 elasticsearch 中搜索答案

【问题标题】：Search in elasticsearch using php curl使用 php curl 在 elasticsearch 中搜索
【发布时间】：2015-03-13 18:50:21
【问题描述】：

我已经使用 elasticsearch 制作了应用程序，除了使用 php curl 进行搜索之外，一切都运行良好；错误如下

[match] query parsed in simplified form, with direct field name, but included more options than just the field name, possibly use its 'options' form, with 'query' element?]

但相同的查询在命令行中运行良好。

当我进行一些更改时，我发现 curl POST 会发生这种情况。

我正在使用以下代码运行 php curl 并尝试了 GET 方法

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 200);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, strtoupper($method));
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($params));
$response = curl_exec($ch);
curl_close ($ch);

查询是

{"query":{"filtered":{"query":{"bool":{"should":[{"bool":{"should":[{"match_phrase":{"name":"india"}}],"boost":16}},{"bool":{"should":[{"match_phrase":{"description":"india"}}],"boost":8}},{"bool":{"should":[{"match":{"name":{"query":"india","analyzer":"standard"}}},{"match":{"description":{"query":"india","analyzer":"standard"}}}],"boost":4}},{"match":{"name.ngram":[{"query":"india","analyzer":"standard"}]}},{"match":{"description":[{"query":"india","analyzer":"standard"}]}},{"match":{"name.ngram":[{"query":"india","analyzer":"standard","fuzziness":"auto"}]}},{"match":{"description":[{"query":"india","analyzer":"standard","fuzziness":"auto"}]}}],"boost":2}},"filter":{"and":[{"terms":{"type":["book"]}},{"range":{"price":{"from":"1","to":"100"}}}]}}},"from":0,"size":20,"filter":{"and":[]},"sort":[{"popularity":{"order":"desc","missing":"_last"}}]}

【问题讨论】：

您的查询是什么？ IE。你把$params传递给了什么？
@king_nak 我已经更新了问题；请立即查找查询

【解决方案1】：

问题可能在于您在查询 dsl 中使用了空白过滤器。

"filter": {
    "and":[]
}

尝试不使用空白过滤器。在 Elasticsearch 1.0 + 版本中，顶级过滤器也被重命名。

更新查询 DSL：

{
   "query": {
      "filtered": {
         "query": {
            "bool": {
               "should": [
                  {
                     "bool": {
                        "should": [
                           {
                              "match_phrase": {
                                 "name": "india"
                              }
                           }
                        ],
                        "boost": 16
                     }

【讨论】：

我已经更新了你给出的查询，它也给出了同样的错误

【解决方案2】：

我找到了解决办法；下面是正确的json

{"query":{"filtered":{"query":{"bool":{"should":[{"bool":{"should":[{"match_phrase":{"name":"india"}}],"boost":16}},{"bool":{"should":[{"match_phrase":{"description":"india"}}],"boost":8}},{"bool":{"should":[{"match":{"name":{"query":"india","analyzer":"standard"}}},{"match":{"description":{"query":"india","analyzer":"standard"}}}],"boost":4}},{"match":{"name.ngram":{"query":"india","analyzer":"standard"}}},{"match":{"description":{"query":"india","analyzer":"standard"}}},{"match":{"name.ngram":{"query":"india","analyzer":"standard","fuzziness":"auto"}}},{"match":{"description":{"query":"india","analyzer":"standard","fuzziness":"auto"}}}],"boost":2}},"filter":[]}},"from":0,"size":20,"sort":[{"popularity":{"order":"desc","missing":"_last"}}]}

问题出在匹配查询阶段；我将匹配查询中的参数附加为嵌套数组。

现在我已经删除了嵌套数组，并将匹配查询阶段的选项附加为顺序数组

感谢大家的配合
