🔖 Feature description

I have noticed that sort by random can generate tasks with the same description on any given day.

Example query:

sort by random
limit 10

For me today is giving:

I want results to be more random, so I get more variety of options in any given day.

✔️ Solution

The relevant code is line 45 here:

obsidian-tasks/src/Query/Filter/RandomField.ts

Lines 29 to 46 in 6967436

	public sortKey(task: Task): number {
	// Credit:

	// - Based on TinySimpleHash in https://stackoverflow.com/a/52171480/104370
	const tinySimpleHash = (s: string): number => {
	let i = 0; // Index for iterating over the string
	let h = 9; // Initial hash value
	while (i < s.length) {
	h = Math.imul(h ^ s.charCodeAt(i++), 9 ** 9);
	}
	return h ^ (h >>> 9);
	};
	const currentDate = window.moment().format('Y-MM-DD');
	return tinySimpleHash(currentDate + ' ' + task.description);
	}

I think it would be worth including the file path in the key, not just the description, for greater diversity of results.
