SOLR 术语频率 [英] SOLR term frequency

问题描述

我正在使用 solr，到目前为止一切都很好.当我进行搜索时，我想获取每个文档中搜索术语"的次数以及文档本身.我已经找到了很多信息，但是经过它之后，我仍然不明白如何做到这一点.有那么难吗?

I am using solr, and so far everything is going great. When I do a search, I want to get back how many times the search 'term' was per document, along with the document itself. I have found alot of information but after going trough it I still don't understand how I can do this. Is it that extreme hard ?

有人可以帮我吗?

虽然我确实得到了结果，但 fl 字段始终为 0

Altough I do get results, the fl field is always 0

http://localhost:8983/solr/collection1/select?q=text:*mySearchTerm*&fl=*,fl:termfreq(text,*mySearchTerm*)

推荐答案

好的，我发现 termfreq 不适用于 MultiValues 字段.所以我使用了一个复制字段并添加了 termVectors="true" termPositions="true" termOffsets="true".现在可以了

Ok, I found out that termfreq doesn't work for MultiValues fields. So I used a copy field and added termVectors="true" termPositions="true" termOffsets="true". Now it works
