[jira] Created: (SOLR-1713) Carrot2 Clustering should have an
option to cluster on a different number of rows than the DocList size
Carrot2 Clustering should have an option to cluster on a different number of rows than the DocList size
-------------------------------------------------------------------------------------------------------
Key: SOLR-1713
URL: https://issues.apache.org/jira/browse/SOLR-1713
Project: Solr
Issue Type: Improvement
Components: contrib - Clustering
Reporter: Grant Ingersoll
It would be nice if, in the Carrot2 clustering, we could only return 10 rows as part of the query, but cluster on more. Alternatively, it may even make sense to be able to cluster on the DocSet, too.

Hi,
I figured out a solution putting all the logic in ClusterComponent. This
component manages the logic between rows parameter and new rows parameters.
The second one is the parameter which defines rows count to be clustered.
I've attached a propousal in Jira. At the end describes an alternative
solution if the first fails to meet the initial expectations
Regards,
Zacarias

I think we want to avoid querying twice. I would query by the max of rows and a new parameter (cluster_rows? internal_rows? Other?) and then reduce the number at the end. It's a little tricky, b/c we likely don't want to couple the QueryComponent to the ClusterComponent, so we may want to make this just a wee bit more generic.

Hi,
I want to solve the
https://issues.apache.org/jira/browse/SOLR-1713improvment but I have
some questions. If somebody can give a little
orientation should be great.
What the issue says is "Query rows=10 but cluster on more"?
If this is what it says, the idea is to solve using results or collection
part of the ClusteringComponent. (Because Collection part uses
DocumentEngine, which is in experimental state).
If the user wants to cluster on more rows, should I query twice or just
query by the biggest quantity of rows and then reduce the number at the end?
Regards,
Zacarias.
