@WeiZhong: This query seems to crash the server: OR content:$\exact{A} \exact{H}^{n-1} \le (n \exact{G})^n$

@MartinR Thank you for reporting this issue. It does not crash the server but the query takes so long time that the client goes timeout. However, if many such queries go to the server, it would potentially crash it. I am looking into it, no idea why this happens.
