Search bar is just appended with new search query instead of cleaing out the prevs. query

I was trying out the example in the README, followed by changing the task to search for a new song.
- It didn't clear our the search bar 
- Just appended `<new_query>+<old_query>`

Also, if i remember right there was a instance where it did `<new_query>+<new_query>+<old_query>` once. Not sure why, missed the logs
