Opening a writer should be a very fast operation, but closing may be
costly since that does a commit() to make the changes permanent in the
IO system.
Still... if you don't need to refresh your searchers you may want to
just leave the writers open, but perhaps lower the RAM buffer if you
don't have enough memory dedicated to the JRE?

Whether it will be a good idea to open writer only when required.
Whether opening writer will take some time as like searcher?
Whether to initialize writer will take some time?

Subject: Re: Writer memory released after flush
IndexWriter holds onto the memory & recycles it. It's best to
close the writer if you need to release the memory.

I am maintaing multiple indexes and all writers will be opened.
Based on some criteria, the document is added to a particular
index. I am using 50 MB of RAM buffer size. Whether the buffer
will be released once flush or optinization done or the writer
will maintain the memory and recyle it.
