Nestor Oviedo commented on DS-1244:
-----------------------------------
I'm not sure what would be the right way with this issue. We thought the best
way to proceed would be to add the open-search match in the Discovery aspect,
but then we realised that, because of the aspect chain execution, the xml
serialized by discovery aspect must be a DRI compatible xml, and the one
generated by the open-search generator is not (we tested this).
A simple way to achieve this might be changing the root sitemap.xmap in order
to catch the "/open-search/discover" requests. This approach requires editing
the "websvc.opensearch.svccontext" config property.
So, the root sitemap.xmap would end up having the following open-search matches:
<!-- catch all open-search requests -->
<map:match pattern="open-search/**">
<!-- non-discovery request (backward compatible) -->
<map:match pattern="open-search/">
<map:generate type="OpenSearchGenerator"/>
</map:match>
<!-- discovery request -->
<map:match pattern="open-search/discover">
<map:generate type="DiscoveryOpenSearchGenerator"/>
</map:match>
<!-- common behaviour for discovery and non-discovery
request -->
....
....
</map:match>
The dspace.cfg file would have:
- without discovery, no need to make changes
websvc.opensearch.uicontext = simple-search
websvc.opensearch.svccontext = open-search/
- with discovery
websvc.opensearch.uicontext = discover
websvc.opensearch.svccontext = open-search/discover
I'd like to hear what you have to say about this issue. Any idea would be very
welcome
> OpenSearch not working as expected when Discovery is enabled

> Key: DS-1244
> URL: https://jira.duraspace.org/browse/DS-1244
> Project: DSpace
> Issue Type: Bug
> Components: Discovery, DSpace API
> Affects Versions: 1.8.2, 3.0
> Reporter: Nestor Oviedo
> Labels: 404, Discovery, OpenSearch, open-search, simple-search
>
> We enabled the Discovery aspect (and disabled the SearchArtifact
> aspect). It seemed there were no problem until we try the OpenSearch
> service.
> There are two main problems here:
> 1) URL "/simple-search" returns a 404 error
> 2) URL "/open-search" is not using Solr services
> About problem 1, that value is defined in the
> "websvc.opensearch.uicontext" property (in dspace.cfg). The DSpace
> manual says it is for HTML requests and should be changed only for
> non-standard servlet mapping.
> As I can see, this property could be changed to "/discover" and the
> OpenSearch returning HTML pages with results would be working as
> expected.
> If this is true, maybe this situation could be added to the DSpace manual.
> About problem 2, I've seen the "/open-search" URL is matched in the
> main sitemap.xmap (the one located in
> <xmlui-webapp>/sitemap.xmap), and a special generator is
> invoked to make the search and to create the RSS/ATOM with the
> results.This special generator is
> org.dspace.app.xmlui.cocoon.OpenSearchGenerator .
> The problem here is that the search is made using the PostgreSQL index
> instead of the Solr services.
> I suspect a brand new generator should be created, which would use the
> Solr services for searching.
> We will be working on this. If anyone has some comment or suggest, it'd be
> very welcome.
