----------------------------------
Yup I know - in the case that that goes in first, its easier to resolve (I had
already put it here). And if it does not, I'll remove it before committing.
> Create a hook to allow custom code to create custom IndexReaders

> I have a customized IndexReader and I want to write a Solr plugin to use my
> derived IndexReader implementation. Currently IndexReader instantiation is
> hard coded to be:
> IndexReader.open(path)
> It would be really useful if this is done thru a plugable factory that can be
> configured, e.g. IndexReaderFactory
> interface IndexReaderFactory{
> IndexReader newReader(String name,String path);
> }
> the default implementation would just return: IndexReader.open(path)
> And in the newSearcher and getSearcher methods in SolrCore class can call the
> current factory implementation to get the IndexReader instance and then build
> the SolrIndexSearcher by passing in the reader.
> It would be really nice to add this improvement soon (This seems to be a
> trivial addition) as our project really depends on this.
> Thanks
