Frequency of the matched string in solr

Question

I am indexing pdfs in my application. I want to show the frequency of the searched string in each pdf. I am using debugQuery=true and parsing the debug result. I am setting debug.explain.structured=true.

For eg: Input-foo then it will list all the pdfs in which this foo occurs. Output-cover.pdf 2 matches found(Just an example)

This works fine but the situation when I search for multiple words. Input- foo AND bar

The format of the debug result changes. Ok fine, I parsed this format also but its giving the frequency of only foo but nor bar.

Can anybody please tell me how to get the frequency of the searched words. I have checked termfrequency but we cant give multiple words there also.

Answer 1

What about using highlighting for that? It will create an entry per match in a doc

Answer 2

您可以在查询中使用构面，它也会返回该构面的计数。
