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。修改后的响应schema.xml索引修改后的 exampledocs 看起来像 查询：

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

响应：

女巫意味着数据已正确存储。 如果我查询第一个存储的地理位置，它工作正常，但如果我搜索第三个或第四个地理位置，solr 不会返回任何结果。 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的问题吗？有什么解决办法吗？

老问题，但它仍然出现在许多 Google 搜索结果中，因此这里有有关多值坐标字段的更多信息：

您可以将以下内容添加到 schema.xml 中：

<fieldType name="location_rpt" class="solr.SpatialRecursivePrefixTreeFieldType"
           spatialContextFactory="com.spatial4j.core.context.jts.JtsSpatialContextFactory"
           distErrPct="0.025"
           maxDistErr="0.000009"
           units="degrees" />

然后使用location_rpt场为多值坐标场，并受益于所有优点Solr 4 的新空间搜索 https://cwiki.apache.org/confluence/display/solr/Spatial+Search#SpatialSearch-SpatialRecursivePrefixTreeFieldType(abbreviatedasRPT) offers.

您还需要添加JTS http://sourceforge.net/projects/jts-topo-suite/如果您使用自定义的spatialContextFactory，请将jar添加到您的solr类路径中。如果您从fieldType定义，多值字段仍然有效，但其他高级功能将不起作用。
