MongoDB和全文搜索是单词的一部分 [英] MongoDB and fulltext search part of the word

问题描述

我需要找到单词的一部分，如果我搜索有关len的内容，请找到len开头的所有单词.

I need to find a part of the word, if i search about len its shut find all the words there starting by len.

我正尝试在MongoDB中使用全文本搜索，当它命中100％的单词而不仅仅是单词的一部分时，它会很好地工作.

i'm trying to use fulltext search in MongoDB and its working well when its hit 100% words and not just a part of the words.

为了让这个问题起作用，我对我抱有沉重的解决之道吗?

Have sombardy a soluion to me to get this issue to working?

可以正常工作的示例代码:

db.getCollection('product').find({
    '$and' : [{
    '$text': {
        '$search' : 'lenovo', // match word
        '$caseSensitive' : false
    },
    '$text': {
        '$search' : 'y50 b50 y700', // synonym prepared
        '$caseSensitive' : false
    }
    }]
})

我想获得相同结果的示例代码:

db.getCollection('product').find({
    '$and' : [{
    '$text': {
        '$search' : 'len',
        '$caseSensitive' : false
    },
    '$text': {
        '$search' : 'y50 b50 y700',
        '$caseSensitive' : false
    }
    }]
})

感谢您的时间，希望我能在MongoDB中进行全文搜索得到帮助

推荐答案

如果您想在mongo中进行全文搜索，则应使用$ regex来使用此查询，

If you want full text search in mongo then you should go with $regex by using this query will be

db.product.find({name:{$regex:/len/i}})
