Hi all!
Just sharing the solution)
I've extended SolrDispatchFilter with my own implementation and did like
this:
...
String core = determineCore(req);
super.doFilter(new CoreRoutingReqWrapper(req, core), response, chain);
...
code for the CoreRoutingReqWrapper class:
class CoreRoutingReqWrapper extends HttpServletRequestWrapper {
private String pathToCore;
public CoreRoutingReqWrapper(HttpServletRequest request, String
core) {
super(request);
pathToCore = "/" + core + request.getServletPath();
}
@Override
public String getServletPath() {
return pathToCore;
}
}
Would be nice to have something like CoreResolver component in Solr
architecture.
Something like this:
interface CoreResolver {
String resolveCore(HttpServlerRequest req);
}
Would make Solr server more customizable.
What do you think?
Thanx,
: as I said we have our own search handler (wrapping handleRequestBody
method
: and adding logic before it) where we convert those custom_paramX
params into
: Solr understandable params like q, fq, facet, etc. Then we delegate to
Solr to
: process them.
:
: So what I want to do is core0 handle things if custom_param1=aaa and
core1 if
: custom_param1=ccc.
Ah.. i think i'm understanding:
* you know you need a custom search handler
* you have a custom search handler that delegates to some other handler
based on some logic
* your customer handler modifies the request params before delegating to
the handler it picks.
* the part you are missing is how to delegate to an entirely differnet
SolrCore.
does that capture your question?
The nutshell is you would need to ask your current SolrCore for access to
the CoreContainer -- then create a new "LocalSolrQueryRequest" and ask
that SolrCore to execute it. one hitch to watch out for is keeping track
of thinkgs like the SolrIndexSearcher used -- because stuff like
"DocList"
values in the response will come from the *other* SolrIndexSearcher, and
you'll need to use that when writting the response out (because the
QueryResponseWriter needs to as the SolrInexSearcher for the stored
fields
from those docids).
(Note: i have never tried this ... there may be other gotcha's i'm not
aware of)
