FindIn plugin example fails when at least 2 keys being looked for are smaller than the smallest key in the db

[randalpinto]

If you have let's say "2013", "2014", "2015" in the database and if you search for ["2011", "2012"] the plugin fails as it goes into:

if (cursor.key > keys[current]) {
result.push(undefined); // key not found
current += 1;
cursor.continue(keys[current]);
}

and then it tries to execute:

cursor.continue("2012") but the current cursor position is "2013" so the operation returns an error.

Granted it is just an example but it was a useful operation for me and I found the issue while trying to use it. I'd vote for it to become an official plugin as large lookups are a lot faster performed like this.

Thank you for bug report.
I will probably implement it as a standalone plugin, since it's indeed quite useful.
