@WeiZhong I think that searches with $\aleph_1$ are good example of situation where searching for arbitrary variables instead of the ones given in the query does not work well. AFAIK the letter $\aleph$ is hardly ever used in mathematics for anything else rather than for cardinals. In Approach0 things like $T_1$, $U_1$, $x_1$ are matches too. Is there some way around this?
