solr fieldcollapsing and maximum group.limit

votes

I'm using Solr 3.4 and FieldCollapsing. I would like to group all messages using FieldCollapsing.

Per default, every group contains only 1 message.

I can modify the numbers of documents per group by changing the Parameter group.limit. That's a bit inconveniently for grouping all available messages to specific groups.

Is there a way to set group.limit to infinite?

The current workaround is to set group.limit to an very high value, which isn't an satisfying solution.

Altough Solr is very good at finding the top documents that match a query, it is bad at retrieving lots of documents. What is your use case ? Does your data reside somewhere else (text files? a database?) where this partition could be performed more efficiently? - jpountz

You can set group.limit to -1. Then you will get infinite documents per group.
