Question

我目前在本地服务器上使用solr 5x并使用Drupal实例生成所有索引。经过大量的配置后，我得到了一点，我对solr的实现非常满意。

然而，我刚才注意到的一个问题是正确的拼写仍被视为拼写错误，仍然会提供建议。

"correctlySpelled":false

正如您在 JSON输出中看到的那样，许可证和车辆这两个字拼写正确且仍被归类为不正确

"spellcheck":{
   "suggestions":[
      "license",
      {
         "numFound":3,
         "startOffset":0,
         "endOffset":7,
         "suggestion":[
            "licensed",
            "licensee",
            "licenser"
         ]
      },
      "vehicle",
      {
         "numFound":3,
         "startOffset":8,
         "endOffset":15,
         "suggestion":[
            "chicle",
            "pedicle",
            "vehiculate"
         ]
      }
   ],
   "correctlySpelled":false,
   "collations":[
      "collation",
      "licensed chicle",
      "collation",
      "licensed pedicle",
      "collation",
      "licensed vehiculate",
      "collation",
      "licenser chicle",
      "collation",
      "licenser pedicle"
   ]
}

有没有人知道为什么会产生误报？

网址编码查询：

http://192.168.33.10:8983/solr/drupal/spell?q=license+vehicle&spellcheck=true&spellcheck.accuracy=0.7&spellcheck.collate=true&defType=edismax&json.nl=flat&omitHeader=true&qf=ts_title^1&fl=*,score&start=0&fq=index_id:"new_index"&fq=hash:"96z3wm"&rows=10&wt=json&stopwords=true&lowercaseOperators=true

查询：

q = license+vehicle
spellcheck = true
spellcheck.accuracy = 0.7
spellcheck.collate = true
defType = edismax
json.nl = flat
omitHeader = true
qf = ts_title^1
fl = *,score
start = 0
fq = index_id:"new_index"
fq = hash:"96z3wm"
rows = 10
wt = json
stopwords = true
lowercaseOperators = true

这也是我与Solr一起经历的事情。它以不可预测的方式发生。我用来避免这种情况的方法是使用edismax参数“mm”进行拼写预检，方法是将其设置为100。尝试在edismax查询中设置mm = 100，看看是否有效。然后你制作一个流程，你的第一个严格的拼写检查单词，然后传递给搜索查询处理程序。如果指定mm = 100，请不要在任何类型的双引号中传递您的短语，只需按原样传递即可。如果有帮助，请告诉我:)。

Solr Spell检查正确返回误报Spelled（）
