@MartinR and others - it would be useful to add some good tips on using Approach0 into the FAQ entry: How to search on this site?
> There is a distinction between
\infty
and +\infty
. For example, you get different results for $\lim_{x\to\infty} (1+\frac1n)^n$ and for $\lim_{x\to+\infty} (1+\frac1n)^n$ then the results are completely different.
I will look a bit through the past posts here, maybe I will be able to think about something else which is worth adding.
Possibly looking at some past comments could help us remember some type of searches where Approach0 was used: data.stackexchange.com/math/query/556789/… and data.stackexchange.com/math/query/556790/…
And here are the chat messages mentioning Approach0: chat.stackexchange.com/search?q=Approach0&room=

> Approach0 is able - at least to some extent - to find posts where the same expression is written differently. (For example, names of a variables are changed, the sides of an equation are exchanged, etc.) But since this have some limits, you should try to think about various ways of writing the same expression.
> For example, when looking for posts about limit of Cesàro mean, you could try to search for $\lim_{n\to\infty}\frac{\sum_{k=1}^n a_k}n$, or for $\lim_{n\to\infty} n^{-1}\left(\sum_{k=1}^n a_k\right)$,
> or for $\lim_{n\to\infty}\frac1n\left(\sum_{k=1}^n a_k\right)$, or for $\lim_{n\to\infty}\frac{a_1+\dots+a_n}n$
