Hi euler,
Is it possible that, at least for the sidebar issue, you could use
HierarchicalSidebarFacetConfiguration to end up with terms split on the
semicolon, and also displayed in a hierarchy so people have to click eg.
"technical report" first, then the series number they're interested in?
You'll find this config in $dspace/config/modules/spring/discovery.xml
Here's how the (out of box) searchFilter version does it, splitting by ::
so that LCSH subjects get split and tiered appropriately
<bean id="searchFilterSubject" class=
"org.dspace.discovery.configuration.HierarchicalSidebarFacetConfiguration">
<property name="indexFieldName" value="subject"/>
<property name="metadataFields">
<list>
<value>dc.subject.*</value>
</list>
</property>
<property name="facetLimit" value="10"/>
<property name="sortOrderSidebar" value="COUNT"/>
<property name="sortOrderFilterPage" value="COUNT"/>
<property name="splitter" value="::"/>
</bean>
You could do something quite similar, such as:
<bean id="searchFilterReportSeries" class=
"org.dspace.discovery.configuration.HierarchicalSidebarFacetConfiguration">
<property name="indexFieldName" value="series"/>
<property name="metadataFields">
<list>
<value>dc.whatever.field.you.use.*</value>
</list>
</property>
<property name="facetLimit" value="10"/>
<property name="sortOrderSidebar" value="COUNT"/>
<property name="sortOrderFilterPage" value="COUNT"/>
<property name="splitter" value=";"/>
</bean>
Just adjust the values like facetLimit, metadataFields (set it to the field
name you're using for the full concatenated value) until it's doing what
you like.
It's possible that other SidebarFacetConfiguration field classes accept a
'splitter' property too, not just the Hierarchical version. If that's the
case, you could also play with that and see if that ends up better than a
strict hierarchy for your needs.
If you need to go further than this, it might be time to think about a
custom bean you can plug into the discovery spring configuration like
edu.yourinstitution.repository.discovery.AggregatedTechnicalReportFilterFacetConfiguration,
that does the splitting and any other manipulation needed at index or query
time. (when I need to get tricky like this, I usually spend some time
playing in the solr schema directly so I know exactly how I want the field
treated at index and query time from solr's perspective)
RE: Browse By, I think all that's necessary for it to work the way you want
is for it to be a filter type as well, but if you don't get it for free in
the hierarchical example above, you might want to look at a non-facet
filter class to go along with the hierarchical facet, hopefully it allows a
splitter property or you might have to make a slightly customised version
of DiscoverySearchFilter. The "title" filter, for example, just looks like
below (and doesn't also appear as a facet)
<bean id="searchFilterTitle" class=
"org.dspace.discovery.configuration.DiscoverySearchFilter">
<property name="indexFieldName" value="title"/>
<property name="metadataFields">
<list>
<value>dc.title</value>
</list>
</property>
</bean>
Hope this helps!
Cheers
Kim
