Jason Rutherglen commented on SOLR-2809:
----------------------------------------
In RT the searchers are cheap. The easiest approach would be to record the
segments and max doc ids used to satisfy phase 1 of a given distributed query,
then send that signature back in subsequent phases. The retry would only be
necessary in the infrequent case of a merge have occurred.
With NRT it's probably best to implement a searcher policy similar to index
deletion policy. Then any timeout / searcher removal system can be implemented
by the user, rather than dictated by Solr.
The described searcher management system belongs in a module in Lucene rather
than Solr, probably in one of Mike's new classes.
