Subject RE: Group.query
Date Wed, 26 Sep 2012 10:18:32 GMT
Thanks. Yes I can do this - but doesn't it mean I need to execute a query per group?

What I really want to do (and I'm sorry I'm not so good at explaining) is to execute one query
for products, and receive results grouped by the groups - but where a particular product may
be found in several groups.

For example, I'd like to execute a query for all products which match "bucket".
There are several products which are "buckets", each of which can belong to several groups.
Would it be possible to generate a query which would return the groups, each with a list of
the buckets?

Example result, with 3 groups, and several products (which may occur in several groups).

  Castle bucket
  Plain bucket
  Castle bucket
  Truck bucket

  Castle bucket
  Large Pony bucket

I hope I understood the question, if so this may be a solution:

Why don't you make the field group for product multiple?


<field name="group" type="string" indexed="true" stored="true"

If the product is a member of group1 and group2, just add both for the product document so
that each product has an array of group. Then you can easily get all products for group1 by
doing query: group:group1
