SOLR Spellcheck没有返回结果

我对solr 6.5.0的拼写检查组件有一个恼人的问题 . 如果我通过拼写检查请求处理程序/ spell运行查询，则查询按预期工作，我会得到错误单词的建议拼写 .

{
  "responseHeader":{
    "status":0,
    "QTime":42},
  "response":{"numFound":0,"start":0,"docs":[]
  },
  "spellcheck":{
    "suggestions":{
      "injary":{
        "numFound":3,
        "startOffset":0,
        "endOffset":6,
        "origFreq":0,
        "suggestion":[{
            "word":"injury",
            "freq":121},
          {
            "word":"inward",
            "freq":3},
          {
            "word":"injure",
            "freq":1}]}},
    "correctlySpelled":false,
    "collations":{
      "collation":{
        "collationQuery":"injury",
        "hits":121,
        "misspellingsAndCorrections":[
          "injary","injury"]},
      "collation":{
        "collationQuery":"inward",
        "hits":3,
        "misspellingsAndCorrections":[
          "injary","inward"]},
      "collation":{
        "collationQuery":"injure",
        "hits":1,
        "misspellingsAndCorrections":[
          "injary","injure"]}}}}

但是如果我通过标准请求处理程序/ select运行查询，我就得不到任何建议 .

{
  "responseHeader":{
    "status":0,
    "QTime":0,
    "params":{
      "q":"injary",
      "indent":"on",
      "spellcheck":"on",
      "wt":"json",
      "_":"1492780436450"}},
  "response":{"numFound":0,"start":0,"docs":[]
  }}

任何帮助将不胜感激 .

我修改了 solrconfig.xml 以将两个请求处理程序放入行中，如下所示，其余的是默认值：
