We are testing Lightning in pilot and noticed something interesting on search. Account names with an apostrophe do not come up in LEX search results, though they do in Classic. In our org, we have an  account named "Moore's".  If I search on "moores" then this account is not on the results page in LEX, though it does show if I search with the apostrophe. We don't use Chatter. Any idea why this is happening?
