HI, i am new to ES so my questions are dumb and simple.i indexed around 4000 docs from database and i experimented with index size and number of documents indexed the Es head is showing variable result summary is down below 1st run index\_name-movies1;index\_size=2.7mb;docs\_indexed=2345 2nd run index\_name-movies2;index\_size=1.7mb;docs\_indexed=1700; my idea was to understand memory usage by indexing same data(from database). my question is why i am getting two different index\_size(both memory and doc wise) while indexing same data? ---
