>From the newSearcher(..) of a CustomEventListener which extends of
AbstractSolrEventListener can access to SolrIndexSearcher and all core
properties but can't get a SolrIndexWriter. Do you now how can I get from
there a SolrIndexWriter? This way I would be able to modify the documents (I
need to modify them depending on values of other documents, that's why I
can't do it with DIH delta-import).
Thanks in advance
