I can confirm, I do this also and posted so elsewhere. But the key is ruthless simplicity. Just a blob of plain text every day and any searchable codes, resist all urges to add formatting, drawings, tables, categories, etc. It's more important to put as few mental obstacles in the way of writing in it as you can, and even if you write a lot every day, it still isn't all that much text, and is pretty easy to manage and search conventionally.
