Russian dictionary lookup

Hello. I’ve noticed an error with the Russian dictionaries. Consider the word возьму. The word to look up is взять but unfortunately the word being looked up is брать

Thank you for your time

Edited to add: It looks like, for wikitonary at least, you can search using the written word - возьму in this case

Also (and I’m not complaining just pointing out), тку is incorrectly pointed to ток instead of ткать. But again using the written word (for Wikitionary) would have been fine
