updated labels not recognized by search

[DMB]

Folks,

Is there a way to force the Trello search engine to consult the current database? 

Here's what's happening:

(1) I search for cards with a particular label, #today

(2) I go to a card from the search, perform a task

(3) I remove the label, so it no longer should show up when I search for #today

(4) I repeat the search, but the card is still there, albeit without the label I removed.

Thanks for any suggestions.
