drawback addindexes method

[Chandan Tamrakar]

 

I found that IndexWriter.addIndexes(Directory[]) always calls optimize
method twice 
I am indexing a documents in batches , i.e I call this method when X no. of
documents are buffered in RAM
Using RAMDirectory . So as the index size grows , optimize method will only
increase by indexing time
 
Can these lines be commented out and call the optimize method only at the
end of indexing process?
 
Your thoughts please
 
Thanks
