Dear DSpace Developers,
[DSpace 1.7.2, XMLUI + Discovery]
I'm using trying to use the related items component of DSpace Discovery but
I need a bit of help with setting up the solr query.
Goal:
I have items in the archive that are derivative of other items in the
archive (in this case images and 3D scans of archaeological artifacts)
I have a field, dc.identifier.barcode which is an internal identifier from
our lab, and I use the field dc.relation.isformatof in the derivative items
to refer to the barcode identifier.
What we'd like is
A) The original items to have "Related Items" links to their derivative
works
B) The derivative items to have "Related Items" linked back to the
original item.
Original [Dspace 1.7.2] RelatedItems.java pertinent lines [133-141]
1 this.queryArgs = prepareDefaultFilters(getView());
2 this.queryArgs.setRows(1);
3
this.queryArgs.add("fl","dc.contributor,dc.contributor.author,handle");
4 this.queryArgs.add("mlt","true");
5
this.queryArgs.add("mlt.fl","dc.contributor,dc.contributor.author,handle");
6 this.queryArgs.add("mlt.mindf","1");
7 this.queryArgs.add("mlt.mintf","1");
8 this.queryArgs.setQuery("handle:" + dso.getHandle());
9 this.queryArgs.setRows(1);
Understanding in English:
From what I understand of the above code (slightly reordered but
including line reference):
1) get the default filters
8) query for handle=dso.getHandle \\The current item handle
2) return only one result
3) return only the following fields "dc.contributor,
dc.contributor.author, handle"
4) we want more like the results of the simple query
5) While searching for more like this, only return "dc.contributor,
dc.contributor.author, handle"
6) While searching for more like this, only return documents that have
at least one term in common, and it must occur at least once.
7) While searching for more like this, only use terms that occur at
least once in a source document \\ ie the document that is the result of
the original query
9) return only one result \\ Again?
Ideas to accomplish goal above:
I thought that I could probably just replace the filter terms in lines 3,
and 5 above with
"dc.identifier.barcode, dc.relation.isformatof, handle"
This did not yield the desired results. Testing it on the Dspace
instance, I recieved several false "Related Items" without a
quickly discernible pattern to them.
I also tried adding the line
this.queryArgs.add("mlt.qf",
"dc.identifier.barcode,dc.relation.isformatof");
With the hopes of specifying the query fields. It did the same thing.
Request:
Does anyone have any ideas or experience with this?
I noticed that in DSpace 1.8 that the guts of in "RelatedItems.java" was
commented out.
Is this a part of discovery that is being abandoned?
Or is there some other mechanism that does the same thing?
Thank You,
Joseph
