If you seach in the Logs (Block, Protection, Deletion, ...) you can enter search
informaiton in the "User" and/or "Title" form field. You will only be able to
find matches if you enter the complete name. It seems not to be possible to only
enter a part of the name
If an article "This is just an example to explain the bug" is deleted, it should
be able to find it in the block log by entering "just an example" and hitting
return. Or "*just an example*".
This would also be very usefull in searching IP(-range)s in the logs.
