Elasticsearch Chinese word Insertion jcseg installation (Ubuntu 14.04)

Search can be said to be a very common development in the scene, the same this time ...

Most of the previous combination is the choice of Mysql + Sphinx, this time because the work is no longer use this combination, although the old combination, but does limit a lot of, and every time with the environment is a problem, very annoying ... This time try to use Elasticsearch + jcseg, because in the document retrieval aspect Elasticsearch do quite good, but to the Chinese environment is poor a very good Chinese word breaker, fortunately, the domestic good Chinese word breaker also has quite many, but I personally still is more recommended Jcseg.

Okay, no more nonsense.

Release Notes:

Elasticsearch I use 1.7.2, but 1.7.3 is also feasible for the following process.

JCSEG is a version that needs 1.9.6
