Integral domain on two lines [duplicate]

This question already has an answer here:

Consider the following integral:

$$\int_{\text{One line \\ Second line}} \text{Loss}\left(\text{Foo, Bar} \vert \alpha\right)$$

which renders: How can I have One line and Second line on two separate and consecutive lines at the bottom of the integral?

• Consider also using $…$ or \begin{align*}…\end{align*} rather than $$.

Your comment here will hopefully help the OP to learn about the differences, and this will be sufficient because the post is a duplicate anyway. In general, when I think an answer should be changed, I simply leave a comment below it and let the author decide. Cheers! – Paul Gessler Apr 30 '15 at 20:30
• @PaulGessler Thanks for explaining that decision, which is perfectly sensible! – Clément Apr 30 '15 at 23:23

$\int_{\substack{\text{One line} \\ \text{Second line}}} \text{Loss}\left(\text{Foo, Bar} \vert \alpha\right)$
$\int_{\begin{subarray}{l}\text{One line} \\ \text{Second line} \end {subarray}} \text{Loss}\left(\text{Foo, Bar} \vert \alpha\right)$
