Switch SolrSearch Implementation to begin utilizing Dismax Query Handler
------------------------------------------------------------------------
Key: DSCR-3
URL: http://jira.dspace.org/jira/browse/DSCR-3
Project: DSpace Discovery Module
Issue Type: Improvement
Reporter: Mark Diggory
Dismax will give us the ability to create extensively customizable default
query behavior in Solr. For instance, JOIN together multiple separate fields
in Search Query under on field id so that we do not need to customize the
fields created by DSpace on the client side.
To give an example:
dc.contributor
dc.contributor.author
dc.contributor.other
By utilizing dismax and creating a default query for dc.contributor in the solr
schema, we can avoid needing to "copy" author and other into contributor to
create the dumbing down effect in the older qualified dublin core. Likewise,
we can easily map this strategy to dc terms and other ontologies to create
"optimized" inference relationships for common searches such as those.
Finally, once we do all this, we will also be able to create something I call
"Facet Workflows" or setting a series of broader and narrower facet
configurations that lead the user through search results that start very
granular with dc.contributor but can be drilled into more and more refined
facets of dc.contributor.author and dc.contributor.other, etc as the user
expands those options.
