Hi
I have a set of collections containing documents with the fields: "a",
"b" and "timestamp"
A LOT of documents and a lot of them have same values for "a", and for
each value of "a" there is only a very limited set of distinct values in
the "b"'s. The "timestamp"-values are different for (almost) all documents.
Can I make a group/distinct query to Solr returning all distinct values
of "a" where "timestamp" is within a certain period of time. If yes,
how? Guess this is just using group of facet, but what is the difference
and which one is best? Do any of them require that the fields has been
"prepared" for grouping/faceting by setting it up in the schema?
Can I make a query to Solr returning all distinct values of "a" where
"timestamp" is within a certain period of time, and also, for each
distinct "a", have the limited set of distinct "b"-values returned? I
guess this will beg grouping/faceting on multiple fields, but can you do
that? Other suggestions on how to achieve this?
Regards, Per Steffensen
