Deal Search Gets Faster

We had successfully upgraded our Deal Search infrastructure to use a newer search engine libraries - KinoSearch. Though KinoSearch is still in its alpha stage, but we had experienced its performance of building indices improved over 40 times than Plucene API in our own benchmark test, pretty much in line with official KinoSearch benchmarks. The move is good for user experiences and also improved system reliability for Plucene used to give us file descriptors leakage under mod_perl framework. Shoppers should experience deal results returned in a more timely manner as we continue to grow our deal database.
