The above link goes to this search: OR content:$\cos x+\cos y+\cos z=1 $, AND content:$ \sin x+\sin y+\sin z=1$, AND site:math.stackexchange.com

AFAICT, this is one of advantages of Approach0 over SearchOnMath. I can search on math for a single formula, such as searching for \cos x+\cos y+\cos z=1. But I do not know how to search for two formulas at the same time.

As in this case, I would like to search for posts/sites which have both \cos x+\cos y+\cos z=1 and \sin x+\sin y+\sin z=1.

If somebody knows how to enter multiple formulas into SearchOnMath, let me know.

I wonder whether we should at at least one example with more than one formula (and maybe also some keywords) to the FAQ post. And maybe also mention possiblity to restrict the domain.

@MartinSleziak Yes, the possibility to connect multiple search terms with AND and to restrict the domain is a huge win for the new release of Approach0. Previously, I used SearchOnMath mainly for cases where there are many results on AoPS, that is not needed anymore. Otherwise I have no experience with SearchOnMath.

@MartinSleziak That is definitely a good idea, in particular since the Guide for New Users does not mention the features.

@WeiZhong: Are there any plans to update the User Guide?

I certainly agree that the examples should be kept here.

After all, as regular users the only way to delete messages in chat is to move them elsewhere - which isn't really deletion.

I'll also remind that the same examples with links to the "official" version have been posted in this room, too: chat.stackexchange.com/transcript/message/58430215#58430215

@MartinSleziak That is very useful. I have “pinned” it now so that it appears in the side bar above the outdated message. And yes, moving to the Trash (eventually) is what I meant, so that future readers are not confused.
