lucene：将查询存储在磁盘上/持久查询

Question

I'm new to Lucene (4.7.1) so I apologise if this is a silly question.

What is the best way for me to store the queries to persist them across sessions? Should I leave them as strings in a DB or is it better to store them as Query objects?

Answer 1

Store them as strings.

Queries are no longer Serializable , although they used to be . Moreover, String representation should consume less storage space. More details are also available here .
