Dear Bill,
First of all, if you consider changing these options from the configuration
file, you need to re-index the browse index afterwards. That's why the first
config may not work for you directly, you need to re-index.
So, the difference between metadata and item is the following: When a browse
index is declared as metadata, when clicked, you are presented with the
distinct values of this metadata field and when a value is pressed you are
presented the items which have this value. When a browse index is declared
as "item", when clicked you are directly presented with the list of items.
In case of the "deprecated" browse DAO indexing, the browse indices declared
as metadata where stored in database in tables whose names starts with
bi_(i)_dis or bi_(i)_dmap, where i is the number declared in the cdg file
for each index. When the brose index is declared as item, then it stored in
the table named "bi_item" and more specifically, each "item" browse index is
bound to a sort column in this table.
DSpace 4, workd by default with solr and discovery, so, the aforementioned
may not take place at all.
Hope this helps,
Kostas

Subject: [Dspace-tech] configuring browse indexes
In dspace 4.0 (or any version in general), I have the choice for :metadata:
for any given webui.browse.index.n of either "metadata" or "item".
Can anyone explain the difference between these two options? For instance,
in the docs I see an example like so for title:
webui.browse.index.3 = title:metadata:dc.title:title:full
In the default dspace.cfg, the example is
webui.browse.index.3 = title:item:title
I am guessing that with "metadata" I'm pulling the data from dc.title
field...What about "item"? Where does that data come from?
Naturally, I'm asking because the latter example works, and the former does
not, but I'm having a hard time understanding why.
Thanks in advance for any pointers!
Regards,
Bill
