bug in the whois/wais query?

Hello,

I have noticed a problem with a person called Matyas Matyas.

I needed him in the RIPE database. I queried the database and got:


whois -h whois.ripe.net "Matyas Matyas"
person:      Dedi Matyas
address:     RADCOM Ltd.
address:     8 Hanechoshet St. Tel-Aviv 69710, Israel
phone:       +972 3 6472694
fax-no:      +972 3 6474681
e-mail:      dedi@localhost
nic-hdl:     DM55-RIPE
notify:      lir@localhost
mnt-by:      NNCC
changed:     steiff@localhost 960225
source:      RIPE

I therefore registered the following person:

person:      Matyas Matyas
address:     HotSoft Tirgu Mures - ROMANIA
address:     O.P. 1, C.P. 172
address:     4300 Tirgu Mures - Romania
phone:       +40 65 16 65 16
fax-no:      +40 65 16 62 90
e-mail:      matyi@localhost
nic-hdl:     MM200-RIPE
notify:      ncc@localhost
changed:     zsako@localhost 960403
source:      RIPE

I queried the database in the same way and I got the same result as the first
time!

Therefore I suspected the person had been registered earlier and I queried
the database with the WAIS option (through telnet info.ripe.net).
I looked for the word "Matyas" and I got three results, one of them was the
object below:

person:      Matyas Matyas
address:     HotSoft Tirgu Mures - ROMANIA
address:     O.P. 1, C.P. 172
address:     4300 Tirgu Mures - Romania
phone:       +40-65-166516
fax-no:      +40-65-166290
e-mail:      matyi@localhost
nic-hdl:     MM184-RIPE
changed:     alina@localhost  960326
source:      RIPE

and two irrelevant person objects, but the person with the NIC-handle
MM200-RIPE was not there!
I got a similar result with a different keyword ("matyi" from the e-mail
address) and again got MM184-RIPE, but not MM200-RIPE.

Is this normal (did I miss something) or is this a bug?
(I see two different problems which might have the same cause:
- why does the whois not give me both MM184-RIPE and MM200-RIPE as an answer to
  the 'whois -h whois.ripe.net "Matyas Matyas"'?
- why does the WAIS not give me the person object MM200-RIPE?
).

I could explain however the behaviour of the WAIS query by the fact that it
does not search the "real" database, but a copy of it, which is updated in
bigger chunks. Is this the explanation for the second problem?
I find no explanation for the first problem though...

In case I missed something please excuse me for polluting your mailbox and 
taking your time...

Best regards,
Janos

PS. I will delete the person MM200-RIPE next week, but I want to leave it there
for the moment in case somebody wishes to investigate the problem.
