ES1.4 Chinese word plugin ik

ES Official only support SMARTCN this Chinese word-breaker, is indexed according to a single word. When searching for a front-end product, all those with this keyword will be indexed. To make an analogy: search for "apple" keyword, usually contains "ping" and "fruit" title will be indexed to. So in order to this demand, find a third-party Chinese word-breaker plug-in. Look at the domestic there are several sub-segmentation plug-ins: ik, ANSJ and mmseg. Finally I chose to use IK.
