使用多值位置字段在solr中搜索

我可以为solr中的位置类型字段索引多个值.修改schema.xml和索引修改的exampledocs 的响应看起来像查询:

  http://192.168.3.19:8983/solr/select?wt=json&indent=true&q=*:*

响应:

  {

巫婆意味着数据存储正确.如果我查询第一个存储的地理位置它工作正常,但如果我搜索第三或第四个地理定位solr返回没有结果.如果我运行以下查询:

http://localhost:8983/solr/select?wt=json&indent=true&q=*:*&fq={!geofilt%20pt=45.17614,-93.87341%20sfield=store%20d=5}

我得到了正确的答案:

{
        "id":"VDBDB1A16",
        "name":"A-DATA V-Series 1GB 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) System Memory - OEM",
        "manu":"A-DATA Technology Inc.",
        "popularity":0,
        "inStock":true,
        "manufacturedate_dt":"2006-02-13T15:26:37Z",
        "payloads":"electronics|0.9 memory|0.1",
        "cat":["electronics","memory"],
        "store":["45.17614,-93.87341","37.7752,-122.4232","38.7752,-122.4232","39.7752,-122.4232"],
        "features":[
          "CAS latency 3,\t 2.7v"]},
      {

But if the query is:

    http://localhost:8983/solr/select?wt=json&indent=true&q=*:*&fq={!geofilt%20pt=38.7752,-122.4232%20sfield=store%20d=50}

我不会得到任何结果.这是solr问题吗？有解决方案吗

老问题,但它仍然存在于许多谷歌搜索结果中,所以这里有更多关于多值坐标字段的信息:

您可以将以下内容添加到schema.xml:

然后将该location_rpt字段用于多值坐标字段,并从Solr 4的新空间搜索提供的所有优势中受益.

如果使用自定义spatialContextFactory,还需要将JTS jar 添加到solr类路径.如果从fieldType定义中删除该参数,则多值字段仍然有效,但其他高级功能则不然.
