推荐答案
我所拥有的足够奇怪.它是如此取决于您的用例和$$需求，尽管这样一个开放式问题几乎没有用.如果您需要XML索引(例如XPath类型查询)，那么FAST是唯一的方法.麻烦的是，它的成本&&&.如果您没有很多硬件或$$$，那么您将永远无法击败Lucene的搜索能力. Lucene的最大优势(可扩展性是它之前的疯狂索引/搜索功能).如果您有几个开发人员愿意编写自己的解析器，令牌化器和查询优化器，那么Lucene不受限制.但是，如果您需要几乎不需维护的COTS解决方案，那么Goggle设备就很难被击败.
Strangely enough I have, sort of. It's so dependent on your use case and $$$ requirements though that such an open ended question is pretty useless. If you need XML indexing, with things like XPath type queries, then FAST is the only way to go. Trouble is, it costs &&&. If you don't have a lot of hardware or $$$ then you will never beat Lucene's searching ability. Lucene's biggest strength (other then it's insanely fst indexing/searching) is it's extensibility. If you have a couple developers willing to write their own parsers, tokenizers, and query optimizers then there are no limits to Lucene. But if you need a COTS solution with almost no upkeep then the Goggle Appliance is pretty hard to beat.
