Re: [dspace-tech] Exclude values in facets

2016-04-21 Thread Rafa Carreres 
H Andrea,

After further investigation, I've found that the filter is being 
applied...but not for the home page.

In other words, I have this configuration in discovery.xml:



   




-dc.contributor.author:"Radio Alcoy"
-dc.contributor.author:"Radio París"



.

 



dc.contributor.author
dc.creator





.

After reindexing, all the references to "Radio Alcoy" or "Radio París" in 
the author facet in communities or collections home page are gone, but the 
author facet in the home page still shows this references.

Having a look at solr.log shows that the default filter query is being 
aplied, indeed:

2016-04-20 18:54:56,985 INFO  org.apache.solr.core.SolrCore @ [search] 
webapp=/solr path=/select 
params={q=*:*=dateIssued.year,handle,search.resourcetype,search.resourceid=0=NOT(withdrawn:true)=NOT(discoverable:false)=
*-dc.contributor.author:"Radio+Alcoy"=-dc.contributor.author:"Radio+París"*=location:m335=dateIssued.year:[*+TO+*]=read:(g0+OR+g0)=dateIssued.year_sort+asc=1=javabin=2}
 
hits=1022 status=0 QTime=81
2016-04-20 18:54:57,003 INFO  org.apache.solr.core.SolrCore @ [search] 
webapp=/solr path=/select 
params={q=*:*=dateIssued.year,handle,search.resourcetype,search.resourceid=0=NOT(withdrawn:true)=NOT(discoverable:false)=-dc.contributor.author:"Radio+Alcoy"=-dc.contributor.author:"Radio+París"=location:m335=location:m335=dateIssued.year:[*+TO+*]=read:(g0+OR+g0)=dateIssued.year_sort+desc=1=javabin=2}
 
hits=1022 status=0 QTime=8

So, why is still "Radio Alcoy" and "Radio París" appearing in the author 
home page facet but not in others?

Regards.

Hi Rafa,
the defaultFilterQueries parameter allows you to limit the result set. 
The facet are automatically build upon the result. This mean that in 
your case you will have in the author facet only Van de Velde, Kevin and 
his coauthors. Also if you write the opposite query, i.e.

-dc.contributor.autor:"Van de Velde, Kevin"
I guess that the result will be not what you expect. No items where Van 
de Velde appears as author will be retrieved, so it will be not included 
in the author facet but I guess that this is more restrictive than what 
you want to achieve.


To exclude a terms from a facet the only way is to prevent such term to 
be indexed and you can do that only customizing the code.


In DSpace-CRIS you can easily achieve such goal implementing an 
EnhancedValueGenerator and using such virtual metadata (i.e. 
item.filteredauhor) in the discovery facet configuration

it.cineca.surplus.ir.defaultvalues.EnhancedValuesGenerator

An example of virtual metadata build using this interface in DSpace-CRIS 
and used in discovery can be found here:

https://github.com/Cineca/DSpace/blob/dspace-5_x_x-cris/dspace-api/src/main/java/it/cineca/surplus/ir/defaultvalues/FulltextInfoGenerator.java
https://github.com/Cineca/DSpace/blob/dspace-5_x_x-cris/dspace/config/spring/cris/cris-metadata-enhancers.xml#L167
https://github.com/Cineca/DSpace/blob/dspace-5_x_x-cris/dspace/config/spring/api/discovery.xml#L1722

Hope this help,
Andrea

I have read the documentation 
(https://wiki.duraspace.org/display/DSDOC5x/Discovery) about discovery 
and "Adding default filter queries (OPTIONAL)".


According to this, if I define something like this:



dc.contributor.author: "Van de Velde, Kevin"



Does it mean that I'll only get "Van de Velde, Kevin" in the author facet?

If so, how could I EXCLUDE a number of author from the facet? What's 
the syntax for this?
