嵌套:QueryParsingException[[multi_match]查询不支持[fields]]；

Question

我是弹性出版社的新手，在Wordpress多网络站点上遇到了一些问题，在尝试执行WP-Query时遇到了这个异常：

由：SearchParseException[未能解析搜索源[{“from”：0,“size”：3,“sort”：[{“_score”：{“order”：“desc”}}],“query”：{“bool”：{“shoul”：[{“multi_match”：{“query”：“test”,“type”：“price”,“fields”：{“0”：“post_title”,“1”：“post_content”,“2”：“post_content”,“3”：“author_name”,“taxomies”：“查询”：“测试”，“字段”：{“0”：“Post_Title”，“1”：“Post_Content”，“2”：“Post_Excerpt”，“3”：“authorname”，“分类法”:[“Post_Tag”，“Category”]}，“multi_match”：{“字段”：{“0”：“Post_Title”，“1”：“Post_Content”，“2”：“Post_Excerpt”，“3”：“author_Name”，“分类法”:[“Post_Tag”，“Category”]}，“查询”：“测试”}，“post_filter”：{“bool”：{“必须”:[{“术语”：{“post_type.raw”:[“post”、“页面”、“附件”、“事件”]}}，{“术语”：{“post_status”:[“发布”、“acf禁用”]}}]}}，“aggs”：{“术语”：{“filter”：{“bool”：{“必须”:[{“术语”：{“post_type.raw”:[“post”、“页面”、“附件”、“事件”]}}，{“术语”：{“post_type.raw”:[“post”、“_status“：[”发布“，”禁用ACF“]}}]}}，”aggs“：{”category“：{”size“：{”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“}},”themes“：{”terms“：10000,”字段“：”terms.themes.slug“}},”story_labels“：{”术语“：{”size“：10000,”字段“：”terms.story_labels.slug“}},”资产-类别“：{”术语“：{”size“：10000,”字段“：”terms.asset-class.slug“}},”区域“：{”术语“：{”size“：10000,”字段“：”terms.region.slug“}},”大小“：{”术语“：{”size“：10000,”字段“：”terms.size.slug“”terms.places.slug“}}，”组织“：{”terms“：{”size“：10000，”field“：”terms.organizations.slug“}}，”people“：{”terms“：10000，”field“：”terms.people.slug“}}}}}}]]；nested:QueryParsingException[[multi_match]查询不支持[fields]]；

当$search_fields获得这些值（数组中的数组）时，会出现这样的问题：

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

多谢帮忙。

你需要平整你的领域：

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