GreetingsNow, i'm using lucene , the version is 4.10.3. For some reason, i called forceMerge(1) in the end,and the final space of the Index Library is 15 GB. . But i found that forceMerge(1) cost a lot of time, and on different machines ,the time differs. Is this caused by the different size of memory of the macheines. One has 24GB memory, the other has 48GB memory. And the machine with 24 GB memory cost nearly 18 hours in forceMerge(1), and the machine with 48 GB memory cost nearly 8 hours in forceMerge(1). I guess the forceMerge(1) needs too much memory, so it costs more time in less memory machine. Am i right ?
Also, can forceMerge(1) speed up the search? Thank you All
