Question

我使用MONGOOSE应用程序在我的NODEJS中实现了MongoDB文本搜索，如果我搜索某些内容，那么结果有时对我来说没有用。

有人可以了解一下文字搜索的行为吗？我做错了什么？

ie.i的名字是＆＃34; Franz＆＃34; - 我搜索＆＃34; Franz＆＃34; - 没有结果我的名字是＆＃34;你是英雄＆＃34; - 我搜索＆＃34;英雄 - 找到它对于其他字段也是如此 - 有时它会找到条目，有时候不是

CommentSchema.index({name:'text',shortDescription:'text',longDescription:'text',"topics.text":'text',geoAreaGeneral:'text',geoAreaSpecific:'text'});

顺便说一句：主题的索引（由topics: [{}]定义）不起作用 - 如何让它工作？

这是我的代码：

  var queryParamFind = {
    "addedDate" : {$lt:dateTimeISO}, 
    'deleted': {$ne:true}
  };

    if(order.includes("addedDate"))
    {queryParamOrder = {"addedDate" : -1}}
    if(order.includes("featured"))
    {queryParamOrder = {"featured" : -1}}
    if(order.includes("upvotes"))
    {queryParamOrder = {"upvotes" : -1}}
    else
    {queryParamOrder = {"addedDate" : -1}}

    if(searchPhrase != 'undefined'){
      if (searchPhrase.length==0)
      {}
      else
      {
      queryParamOrder= { "score": { "$meta": "textScore" } };
      queryParamFind= { "$text": { "$search": searchPhrase  }, 'deleted': {$ne:true}};
      queryParamSelect = { "score": { "$meta": "textScore" } };   
      }

    };

  Comment.find(queryParamFind)
        .select(queryParamSelect)
        .populate("addedBy")
        .sort(queryParamOrder)
        .limit(page * onePage)
        .exec(function(err, result){
    if(err){ return next(err); }
    res.json(result);
  });

例如

：

    "topics": [{
        "text": "Tag3000"
    }],
    "__v": NumberInt(0)
}

当我搜索＆＃34;你好＆＃34; - 我只看到＆＃34;你好我的名字是＆＃34;条目

当我搜索＆＃34;评论＆＃34; - 没什么

当我搜索＆＃34;请找到＆＃34; - 发现＆＃34;这是一个新评论＆＃34;条目

当我搜索＆＃34; Fiind＆＃34; - 发现＆＃34;我的名字是你好＆＃34;

当我搜索＆＃34; North＆＃34; - 没什么
