使用的是levelDB存储索引，不过目前没有明白，对于倒排索引，其是否适合？类似思路还有：

Library implementing the storage and the query evaluation for a text search engine. It uses on a key value store database interface to store its data. Currently there exists an implementation based on the google LevelDB library. http://www.project-strus.net

使用lucene做全文搜索的数据库：

不过按照我的观点看，搜索引擎本质上是针对各个field的特定搜索word的列存储。所以其底层实现用tokuDB线性树应该更合适，时间序列。
