Subject weak documents
Date Wed, 27 Nov 2013 08:13:14 GMT

I am relatively new to SOLR and I am looking for a neat way to implement 
weak documents with SOLR.

Whenever a document is updated or deleted all it's dependent documents 
should be removed from the index. In other words they exist as long as 
the document exist they refer to when they were indexed - in that 
specific version. On "update" they will be indexed after their master 

I could like to have some kind of "dependsOn" field that carries the 
uniqueKey value of the master document.

Can this be done efficiently with SOLR?

I need this technique because on update and on delete I don't know how 
many dependent documents exists in the SOLR index. Especially for batch 
index processes, I need a more efficient way than query before every 
update or delete.

kind regards,
