I'm encountering a similar error to Toucan with respect to the spacing. If I enter a query "MIT is", Google is returning results that include "is" as part of a larger word. Ex: "MIT Israel divestment". I'd like to query "MIT is " -- including the space -- but it looks like your query strips it out. I think this fix would return much better results.
Also, it looks like even when returning the result "MIT Israel divestment," the returned result is stripping the first few characters. Examples:
ael divest ael divestment ael investment sael stock aeli stock samic society amic studies overrated tes
