Is eav sorted by v? I'm pretty sure that's the case but I want to make sure.
https://github.com/tonsky/datascript/wiki/Tips-&-tricks#getting-top-10-entities-by-some-attribute kinda indicates it but it's specifically talking about ave.
https://github.com/kristianmandrup/datascript-tutorial/blob/7d2b684611061ab117101317fe5059c6377d8728/datascript_architecture.md#db says that each index is a sorted set of datoms. Although it's not explicit enough that I'm not worried about it. Like, it's not only sorted by ea and is also sorted by v , right?
Thanks!
the index names refer to the sort order, eav is sorted by entity, attribibute, value

Ok, great. So it's sorted by value too. That's what I was sweating.
https://github.com/tonsky/datascript/blob/master/src/datascript/db.cljc#L493-L512 is where the comparison functions are defined
https://github.com/tonsky/datascript/blob/master/src/datascript/db.cljc#L975-L977 is where the sorted sets using the comparison functions are created for each index

Thank you! I got lost when I tried looking through the code.
