Hi All,
I am a new user of Solr.
We are now trying to enable searching on Digg dataset.
It has story_id as the primary key and comment_id are the comment id
which commented story_id, so story_id and comment_id is one-to-many
relationship.
These comment_ids can be replied by some repliers, so comment_id and
repliers are one-to-many relationship.
The problem is that within a single returned document the search results
shows an array of comment_ids and an array of repliers without knowing
which repliers replied which comment.
For example: now we got comment_id:[c1,c,2...,cn],
repliers:[r1,r2,r3....rm]. Can we get something like
comment_id:[c1,c,2...,cn], repliers:[{r1,r2},{},r3....{rm-1,rm}] so that
{r1,r2} is corresponding to c1?
Our current data-config is attached:
