"Filter Examples Message: Dangling meta character ' ' near index 0 1 ^"

Hi Guys,

In many situations I would like to filter examples by the label attribute. In this case my labels are +1 and -1.

When I filter on 'label=-1' it works fine when I filter on 'label=+1' it fails with Message: Dangling meta character '+' near index 0+1^

What are my options here? I have tried various combinations of quotes in the attribute value filter but nothing seems to work. I guess I can change labels back and forth before and after filtering but that seems very dumb.

What are the restrictions for the attribute filter? It seems very sensitive to white space.

Thanks,
-Gagi

    Hi,
    the question of question is: Is your label nominal or numerical? If it is numerical, simply omit the + as usual in daily life. (Or have you seen someone buying a newspaper for +2,40โ‚ฌ? :) )
    And yes: Unfortunately, it's very sensitive to white spaces. We will try to improve that filtering with coming versions.
