The index and sync

Your notes live in two places: on the phone, and in an Opensolr Index that belongs to your account.

At the first sign-in on an account without one, the app creates an index named notes_<install id>__dense, an index with vector embeddings on the same schema Opensolr uses for site search, so the search page and the chat work on it like on any other. Its name is in Settings → Account, and it is listed with your other indexes in the control panel.

Every other phone signed in to the same account uses that same index, so all of them see the same notes. See Signing in.

• Phone first. A note is saved on the phone the moment you save it, then sent to the index right away, in one quick step. Until it is there, the list says not synced yet under it.
• Pull down the list, or Sync now in Settings, to send what is waiting and bring in what changed on another phone that shares the index. The app also syncs when it opens. A sync with nothing new is over in a moment and costs next to nothing.
• A deleted note leaves the index at once and disappears from your other phones at their next sync. It stays deleted, even when another phone still had an edit of it waiting to be sent.
• The order you drag notes into is synced too: your other phones and the search page show the same order, and the phone that ordered the notes last wins.

When a new version of the app needs a newer setup of the notes index, the app brings the index up to date on its own, the first time it opens. Your notes are set aside, the index is changed, and every note is put back and checked before the index is used again. While that runs, what you write stays on the phone as not synced yet and goes up as soon as it is done. There is nothing to do in the control panel.

When your account has a notes index, the top menu of the opensolr.com control panel shows Services → Opensolr Notes, which opens the search page. The index itself is managed like any other: its password and security under Index password and security in the app’s Settings, its disk space and bandwidth counted against your plan.
