Hi Simon, I have stepped into the program. The cause of the null argument is that when I get the hits object after one query, the method of Hits.id throws exceptions. The essential cause is the invalid handle. What should I do?

Could be the "java.lang.IllegalArgumentException: Argument cannot be null" the cause of your problem. Rootcauses of exceptions are always the bottom aren't they? simon On 8/1/06, zhu jiang <[EMAIL PROTECTED]> wrote: > Hi Erik, > > I use multi-threads to add lots of documents while querying.
