// This value is to ignore small raw files when building index.
|
|
// The reason is:
|
|
// 1. The performance of brute-search for small raw files could be better than small index file.
|
|
// 2. And small raw files can be merged to larger files, thus reduce fragmented files count.
|
|
// We decide the value based on a testing for small size raw/index files.
