Retrieving one object
I have stored multiple objects with the values;
uniqueUri
name
timestamp.
There can be multiple object with the same name, but they will have
different timestamps (and different uniqueUri)
I want to retrieve the object of a given name with the latest timestamp. As
an example I might have
1. uniqueUri=99661, name=FOO, timestamp=1355174089270
2. uniqueUri=98765, name=FOO, timestamp=1355174089870
I want to retrieve only object 2.
I have tried retrieving 1 row and sorting DECENDING on timestamp, but this
still returns the first object.
How can I do this?

My mistake;
I was using the embedded SOLR server. I was storing in one route and
searching through another. The changes from the storage wasnt visible (file
open) for the search.
Changing to use the standalone server solved the problem.

Are you sure it stored both? If you search for name:FOO, do you get both?
If not, check which field is your uniqueKey set in schema.xml. Maybe it is
something that was not being changed between the entries and you updated
old record instead.
Also, what field type is your timestamp? Maybe your sort is doing something
different from what your expect.

Alex.
