]
Sanne Grinovero updated HSEARCH-222:
------------------------------------
Description:
As we update an entity by deleting it from index by using an IndexReader, and afterwards
we reinsert it
using an IndexWriter, there is a point in time in the middle were no DPlock is held on the
Directory,
At this moment a ReaderProvider could (re)open the index and
all searches performed on this IndexReader will not find the entity at all.
We should use a Read/Write Lock on DP instead of the current ReentrantLock to use a write
lock during index updates and avoid creating a bottleneck for different threads needing a
searcher.
