使用多值位置字段在solr中搜索

Question

我可以为solr中的位置类型字段索引多个值。 修改后的schema.xml和索引修改后的exampledocs的响应类似于查询：

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

响应：

{
    "id":"TWINX2048-3200PRO",
    "name":"CORSAIR  XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) Dual Channel Kit System Memory - Retail",

    "cat":["electronics","memory"],
    "store":["37.7752,-122.4232","37.7752,-122.4232","38.7752,-122.4232","39.7752,-122.4232"],
    "features":[
      "CAS latency 2,\t2-3-3-6 timing, 2.75v, unbuffered, heat-spreader"]},
  {
    "id":"VS1GB400C3",
    "name":"CORSAIR ValueSelect 1GB 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) System Memory - Retail",

    "store":["37.7752,-100.0232","37.7752,-122.4232","38.7752,-122.4232","39.7752,-122.4232"]},
  {
    "id":"VDBDB1A16",
    "name":"A-DATA V-Series 1GB 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) System Memory - OEM",

    "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"]},
  {

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

Answer 1

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：

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

然后将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。

Answer 2

根据vuky在d whelan的回答中提到的票证（SOLR-2154），这应该是在所有新的Solr版本中。 这是通过机票SOLR-3304（ https://issues.apache.org/jira/browse/SOLR-3304 ）修复的，该机票已于2012年9月17日标记为已修复。

我无法真正找到它应该起作用的特定版本，但我想如果我阅读门票中的注释，2013年5月之后发布的所有内容都应该有效。

Answer 3

LatLon类型不能是多值的。
