Can you use batching?

If not, format you response in an External Method (maybe PythonScript
will do, too. But due to many security checks, it will be significantly
slower then the External Method).

I did not see similar freezing, also my client, too, wants to
have search results with several thousand elements to
export them into Excel for analysis (?).
Usually, IE does not allow that because it times out before
the huge CSV file is generated.
