Hi Alex,

I created a gist with my experiments:

The last technique (using query_string with whitespace analyser) does not
seem to work consistently. Is this a bug or I am doing it wrong? Shall I
open a ticket for this?

Regards,
Lukas

Hi Lukas,

It will be very interesting to compare notes. I will be out of town for
few days and may not be able to conclude my test so lets touch base next
week if it's ok with you

It seems to be related to your use of the keyword tokenizer.

When using the standard tokenizer, it works:
