Pager seeker doesn't work when entering a word

I have a page called -ικός in my graph.
However, when I try to create a link to it and start typing its name, the autocompletor doesn’t find it.

[[-]] - nothing
[[-ι]] - nothing
[[-ικ]] - nothing
[[-ικό]] - nothing
[[-ικός]] - finds it finally

Seems to be a bug.
