> Hello Gentlemen,

> I was doing some testing with ManyAssociation, where I was adding many(~200) number of
entities to this ManyAssociation property. For Index/Query here is ElasticSearch.
> So, when I was executing this test case it failed and throws an "ElasticSearchIndexException".
This is only occurred when trying to associate entities up to some limit (works perfectly
with ~100 entities in this case, but throws exception when we try to associate ~200), and
this limit vary upon entity size.
