Re: [Dspace-tech] discovery facet by collection

Christian Scheible Fri, 24 Jul 2015 06:56:07 -0700

Hi Pablo,

I think the problem is that collection is not a metadata field. So youneed to add some fields to the Solr index.I wrote a pull request (https://github.com/DSpace/DSpace/pull/988) tomake filtering for items with full text possible.


This is possible by:

- adding a FilterPlugin like mydspace-api/src/main/java/org/dspace/discovery/SolrServiceFullTextFilterPlugin.java- referencing it in the discovery.xml to activate it (see line 36 in mypull request).

- and using it the same way I used it (in lines 414-423)

Hope this helps
Christian

My problem is not about making the sidebar facet appear in
community/collection level, the problem is that in nowhere appears it. This
is my discovery.xml of a clean 5.2 version with the collection search filter
configured not working:

if I change the <value>location.coll</value> for
<value>dc.date.issued</value> the sidebar works flawless!
