solr查询:匹配n个单词中的x个 [英] solr query: x out of n words matched

问题描述

据说我有4个单词(为方便起见，我们称它们为a,b,c和d)，我想在solr中进行搜索以匹配其中的3. 我可以编写具有所有排列的查询，如下所示:

supposedly I have 4 words (let's call them a,b,candd for sake of example) and I want to search in solr to match 3 of these. I could write a query with all the permutations as follows:

(a AND b AND c)OR(a AND b AND d)OR(b AND c and d)

这将起作用，并将文档与这4个单词中的3个匹配.

This will work and matches documents with 3 of these 4 words.

但是当我有10个单词并且需要匹配其中3个单词时，事情就会变得混乱. 所需的排列数量呈指数增长.

but things get messy when I have 10 words and need to match 3 of them. The number of permutations required grows exponentially.

显然，由于查询的复杂性，solr崩溃了(响应太慢了)

obviously thanks to the complexity of the query solr goes busted(it gets too slow to respond)

我已经在Internet上进行了搜索，以查找是否有特殊命令可用于此类操作.我什么都找不到.我只是想知道是否有任何技巧可以完成这样的事情.

I've searched all over internet to find out if there is a special command I could use for something like this. I couldn't find anything. I'm just wondering if there is any tricks that could be done to accomplish something like this.
