You can use the Luke request handler to request all the fields in the
index, in case that helps with your UI. Solr's Schema Browser uses
that request handler to introspect. And Solr Flare also uses it to
figure out which fields to show as facets.

We've been building a UI which displays the results in a tabular

this out in our overall system design, such as the UI or application
layer. Given our current thought is to do it at the UI level, check
if the tag is returned or not, I still wanted to check if it's at
all possible to make Solr return empty field tags.
We have several data sets within our index that we've fitted into
our schema, so that even though the field is indexed and stored,
documes may not have data for that field and may be empty when
indexed.
So hence my query to the group.

This is kind of an unusual request, what higher-level problem are
you trying to solve here? Because the field just *isn't there* in
the underlying Lucene index for that document.
I suppose you could index a "not there" token and just throw those
values out from the response...

I have a field Title and Summary. I've currently not set a default
value for the Summary in my schema, it's just a text field with
indexed=true and stored=true, but not required. When the data is
indexed sometimes the documents don't have a summary so then Solr
doesn't index that field.
When a query is sent and we get the results for those documents
returned, if they did not have a summary then there is no tagged in
the xml for that field.
Is there a way to have the xml always return the field tags for each
document in the result set even if the field has no data?
I apologize ahead of time if this has been answered, but after
doing a
bit of search have not been able to find the answer elsewhere.
Thanks
