Debug Queries field explaination

[Swapnil Pande]

Hi ,
Being an amateur in solr i wanted to learn how solr queries internally and
how score is calculated.
So setting debug=true.
I get a json with fields like 'fromSetSize' , 'toSetSize'.. etc.
Can I get a reference link to understand what these exactly mean.

Thanks.

Embedded documents in solr

[Swapnil Pande]

Hi ,
I am new to solr. I am facing a problem for embedding documents to solr. I
dont want to use solr joins.
The document is similar to
{"name":string, availabilities:[{"day":Date,"status":0}..{}]}
I want to index the array and search with queries like

1) where name = 'xyz' and availabilities.day = Date.current  and status =0

Can you provide me the alternative solution to index this type of documents
in solr.
