【问题描述】：

我是 Elastic press 的新手，在 Wordpress 多网络站点上遇到了一些问题，并且在尝试执行 WP-query 时遇到了这个异常：

原因：SearchParseException[无法解析搜索源["from":0,"size":3,"sort":["_score":"order":"desc"]," query":"bool":"should":["multi_match":"query":"test","type":"phrase","fields":"0":"post_title"," 1":"post_content","2":"post_excerpt","3":"author_name","taxonomies":["post_tag","category"],"boost":4,"fuzziness":0, "operator":"and","multi_match":"query":"test","fields":"0":"post_title","1":"post_content","2":" post_excerpt","3":"author_name","taxonomies":["post_tag","category"],"boost":2,"fuzziness":0,"multi_match":"fields": "0":"post_title","1":"post_content","2":"post_excerpt","3":"author_name","分类法":["post_tag","category"],"查询":"test","fuzziness":0,"operator":"and"],"post_filter":"bool":"must":["terms":"post_type.raw ":["post","page","attachment","events"],"terms":"post_status":["publish","acf-disabled"]]," aggs":"terms":"filter":"bool":"must":["terms":"post_type.raw":["post","page","attachment","事件"],"条款":"p ost_status":["publish","acf-disabled"]],"aggs":"category":"terms":"size":10000,"field":"terms.category. slug","post_tag":"terms":"size":10000,"field":"terms.post_tag.slug","post_format":"terms":"size":10000 ,"field":"terms.post_format.slug","key_themes":"terms":"size":10000,"field":"terms.key_themes.slug","themes": "terms":"size":10000,"field":"terms.themes.slug","story_labels":"terms":"size":10000,"field":"terms.story_labels. slug","asset-class":"terms":"size":10000,"field":"terms.asset-class.slug","region":"terms":"大小":10000,"字段":"terms.region.slug","大小":"terms":"size":10000,"field":"terms.size.slug","地方":"terms":"size":10000,"field":"terms.places.slug","organizations":"terms":"size":10000,"field":" terms.organizations.slug","people":"terms":"size":10000,"field":"terms.people.slug"]];嵌套：QueryParsingException[[multi_match] 查询不支持 [fields]];

    return $formatted_args;

导致这种情况的问题是当 $search_fields 得到这个值时（数组中的数组）：

$search_fields = array(
            'post_title',
            'post_content',
            'post_excerpt',
            'author_name',
            'taxonomies' => array(
                'post_tag',
                'category',
            )
        );

感谢您的帮助。

【参考方案1】：

你需要展平你的领域：

 $search_fields = array(
                'post_title',
                'post_content',
                'post_excerpt',
                'author_name',
                'taxonomies.post_tag',
                'taxonomies.category'
   );
