Assume I have an index of size 20G and a main memory of 1G.
I do the following steps in order.
* Open an IndexSearcher on the directory.
* Serve Searches from that directory
Meanwhile (when the IndexSearcher isstill open on the directory) - the
following operations are performed concurrently.
* Open an IndexReader on the same directory
* invoke delete on the same ( which I believe, internally should 'touch'
some records in segments and mark them as deleted. The 'touch'ed records
across segments are removed when the index is 'optimize'd. At this point
, though the index is not 'optimize'd but just 'commit'ted ).
When the IndexReader is performing a delete operation on a data
directory , how would it affect the IndexSearcher that possibly might be
trying to return search results for a given input query. Would it be
possible for the searcher to crash , when the searcher and reader are
accessing the same set of resources (it seems logically correct for the
searcher to crash though).
