我正在尝试让 Solr SpellCheckComponent 工作，但遇到了一些问题。当我运行 .../solr/collection1/select?q= %3A &wt=json&indent=true

返回这些结果

{
  "responseHeader": {
    "status": 0,
    "QTime": 1,
    "params": {
      "indent": "true",
      "q": "*:*",
      "_": "1379457032534",
      "wt": "json"
    }
  },
  "response": {
    "numFound": 2,
    "start": 0,
    "docs": [
      {
        "enterprise_name": "because",
        "name": "doc1",
        "enterprise_id": "100",
        "_version_": 1446463888248799200
      },
      {
        "enterprise_name": "what",
        "name": "RZTEST",
        "enterprise_id": "102",
        "_version_": 1446464432735518700
      }
    ]
  }
}

这些是我索引的值。现在，当我想查询拼写时，我得到了一些奇怪的结果。

当我运行 /solr/collection1/select?q=name%3Arxtest&wt=json&indent=true&spellcheck=true

结果是准确的，我得到了

{
      "responseHeader":{
        "status":0,
        "QTime":4,
        "params":{
          "spellcheck":"true",
          "indent":"true",
          "q":"name:rxtest",
          "wt":"json"}},
      "response":{"numFound":0,"start":0,"docs":[]
      },
      "spellcheck":{
        "suggestions":[
          "rxtest",{
            "numFound":1,
            "startOffset":5,
            "endOffset":11,
            "suggestion":["rztest"]}]}}

每当我运行没有名称值的查询时，我都会得到 0 个结果。/solr/collection1/select?q=enterprise_name%3Abecaus&wt=json&indent=true&spellcheck=true

{
  "responseHeader":{
    "status":0,
    "QTime":5,
    "params":{
      "spellcheck":"true",
      "indent":"true",
      "q":"enterprise_name:becaus",
      "wt":"json"}},
  "response":{"numFound":0,"start":0,"docs":[]
  },
  "spellcheck":{
    "suggestions":[]}}

我的猜测是我的方案有问题，但一切看起来都很好。

任何帮助将不胜感激，谢谢

我想到了！

所以只有名称起作用的原因是因为名称是 solrconfig 中配置的唯一字段。一旦我这样做了，我就按照这个链接来解决剩下的问题。

SOLR 建议器多字段自动完成
