solr查询返回长度为1的doclist，尽管numfound大于1

当使用group by字段查询solr时，我发现“num_found”大于1的响应，但“docs”属性仅显示1条记录

查询类似于：

http://.../solr/.../select?q=*%3A*&fq=...&wt=json&indent=true&group=true&group.field=GroupingField_s&group.ngroups=true

"grouped": {
    "GroupingField_s": {
      "matches": 3130,
      "ngroups": 283,
      "groups": [
        {
          "groupValue": "1111",
          "doclist": {
            "numFound": 7,
            "start": 0,
            "docs": [ {/*only 1 record shown here*/} ]
         },
        {
          "groupValue": "222",
          "doclist": {
            "numFound": 5,
            "start": 0,
            "docs": [ {/*only 1 record shown here*/} ]
        }, ....
     ]
}

结果如下：

http://.../solr/.../select?q=*%3A*&fq=...&wt=json&indent=true&group=true&group.field=GroupingField_s&group.ngroups=true

"grouped": {
    "GroupingField_s": {
      "matches": 3130,
      "ngroups": 283,
      "groups": [
        {
          "groupValue": "1111",
          "doclist": {
            "numFound": 7,
            "start": 0,
            "docs": [ {/*only 1 record shown here*/} ]
         },
        {
          "groupValue": "222",
          "doclist": {
            "numFound": 5,
            "start": 0,
            "docs": [ {/*only 1 record shown here*/} ]
        }, ....
     ]
}

您必须设置

group.limit

参数。这默认为1

group.limitinteger指定每个组要返回的结果数。默认值为1
