You can create your own Codec and implement your own formats, e.g. PostingsFormat controls how postings are encoded on disk. It's best to let the OS load the index into RAM ... as long as you have enough free RAM, the OS will use it to cache all hot pages from the index. We do have a RAMDirectory

Directly use inverted index

2013-07-27 Thread Airway Wong

Hi, I would like to use Lucene's inverted index directly as building block for experimental purpose. 1. How can I customize the inverted list for different format? Is there any example? 2. Is there an easy way to force load the complete index into memory? Thanks in advance.
