Thank you in advance.

Answer 1

Nutch（ Lucene ）是一个开源引擎，可以满足您的需求。

Answer 2

In the past I worked with terrier , a search engine written in Java:

Terrier is a highly flexible, efficient, effective, and robust search engine, readily deployable on large-scale collections of documents. Terrier implements state-of-the-art indexing and retrieval functionalities. Terrier provides an ideal platform for the rapid development of large-scale retrieval applications.

Answer 3

I've spent the last 2 years developing our own high performance search engine with C. For Java I highly suggest Apache Lucene as Ajay mentioned above. For Java, it's the best in terms of speed, relevancy and features.
