Question

Mercury · Answer

putting quotes around text will result in searches that only contain those exact words in that order. there could be a lot of helpful sources about this topic, that don't contain those exact words in that order. therefore, the most appropriate suggestion is to change the key words.

however, the other suggestions are also possible ways to improve the results of the search. so I would say all of the above.
