Deleting and committing inside a SearchComponent
Hi
Is it possible to delete and commit updates to an index inside a custom SearchComponent? I know I can do it with solrj but due to several business logic requirements I need to build the logic inside the search component. I am using SOLR 4.5.0.
thank you

I agree with Upayavira. This seems architecturally
questionable.
In your example, the crux of the matter is
"Only differ by one field". Figuring that out is going to
be expensive, are you burdening searches with this
kind of logic?
Why not create a custom update processor that does
this and use such a component? Or build it into
your updates when you ingest the docs? Or build
a signature field and issue a delete by query on that
when you update?
Best,
Erick

i can think of many situations that it makes sense. for instance, you search for a document and your index contains many duplicates that only differ by one field, such as the time they were indexed (think news feeds from multiple sources). So after the search we want to delete the duplicate documents that satisfy some policy (here date, but it could be some other policy).

Solution i am working with
UpdateRequestProcessorChain processorChain = rb.req.getCore().getUpdateProcessingChain(rb.req.getParams().get(UpdateParams.UPDATE_CHAIN));
UpdateRequestProcessor processor = processorChain.createProcessor(rb.req, rb.rsp);
...
docId = f();
...
DeleteUpdateCommand cmd = new DeleteUpdateCommand(req);
cmd.setId(docId.toString());
processor.processDelete(cmd);

That just doesn't make sense. Search components are read only.
What are you trying to do? What stuff do you need to change? Could you
do it within an UpdateProcessor?
