Example search starting with numeral returns wrong results #803

An example search starting with a numeral followed by kana returns too many reaults. E.g. search on 3まい returns all examples containing 3 even if not followed by まい i.e . ３か, ３に, 3じ etc. This is the same as if you search just on 3. This makes it hard to search for examples using counters.
I wouldn't say this is urgent but I just came across it and thought it was worth mentioning.
