Question

如果我们删除datastax cassandra中的一行，DataStax将删除solr中的所有字段，但保留其ID（uniqueKey）字段。这个uniqueKey字段在solr搜索中被索引，没有所有其他字段的数据。如何在solr中删除这个uniqueKey值？

示例搜索结果（第一个文档只有uniqueKey值，但此记录在数据库中删除）：

 {
        "groupValue":"b00naxzgps",
      "doclist":{"numFound":1,"start":0,"docs":[
          {
            "_uniqueKey":"[\"B00NAXZGPS\",\"1439337600000\",\"5790.0\",\"Amazon\"]"}]
      }},
    {
      "groupValue":"acce3f2aybn5yyht",
      "doclist":{"numFound":9,"start":0,"docs":[
          {
            "_uniqueKey":"[\"ACCE3F2AYBN5YYHT\",\"1439942400000\",\"349.0\",\"Flipkart\"]",
            "product_id":"ACCE3F2AYBN5YYHT",
            "location":"null",
            "product_name":"Airnet USB for ZTE Blade G2 Car Charger",
            "state":"null",
            "address1":"null",
            "address2":"null",
            "updated_time":"2015-08-19T17:47:28.876Z",
            "product_group":"mobile_accessories",
            "city":"null",
            "updated_date":"2015-08-19T00:00:00Z",
            "longitude":0.0,
            "user_id":"null",
            "imageurl":"null",
            "currency_code":"INR",
            "mrp_price":699.0}]
      }},

删除不删除solr文档中的ID
