回复： Why does this query slow down Lucene?
The query has been stuck for more than an hour. The total size is less than 1G, and the number of docs is around 100,000. Hardware is ok as it works well with other much more demanding projects.

how slow is it？ are all your searches slow or only that query slow？ how
many docs are indexed and the size of the indexes？ whats the hardware
configuration？
you should describe it clearly to get help.

and also try jmap -heap pid to check whether it runs out of memory
or jstat -gcutil pid 1000
