remotely-save VS obsidian-omnisearch

You're not and you're actually reinventing the wheel as a couple of options for that are already available as community plugins. I've been using Remote-save for a while with a almost free private S3 bucket and encryption to sync between my computers and phone for a while.

It supports more than just S3 (as is listed in the README), its just what I use.

There's an Obisidian plugin for direct syncing to OneDrive that works on both mobile and desktop - this keeps you from having to deal with either triggered syncs through github or the various other, painful syncing processes.

I didn't try any of them to be honest. But I remember seeing a couple of posts mentioning their drawbacks. With that said, you may follow this documentation on how to connect your DropBox.

What are the specific advantages of using Remotely Save plugin compared to simply saving the vault in OneDrive?

I use Remotely Save plugin synced with a free tier OneDrive (sadly gdrive isn't supported) and it works very well. Maybe if you not find any alternatives good enought (most of then are a bit hard to setup and maintain) and do not want to pay the official sync plugin than this may work for you as worked for me.

You can use Remotely Save plug-in. It is a life saver for me to sync between different devices.

I'm currently using Remotely save without problems between Windows, iPad and Android.

My Nextcloud instance also synchronizes my Obsidian vault so highlits after uploading are available also there on desktop. On mobile I also use Obsidian with remotely-save plugin https://github.com/remotely-save/remotely-save so I have access to all uploaded files.

Mobile Document Scanning using QuickScan iOS app and OCR search with Omnisearch and Text Extractor: I was a power user of the Scannable app by Evernote for capturing scans of receipts and documents, so moving on from this was going to be tough. But QuickScan has the same functionality (OCR scanning) and has quick outputs to where my scans are stored in my Obsidian folder. Using Omnisearch, searching my scans feels just as intuitive and snappy as what Evernote used to feel like for me.

In the past I have used Omnisearch which I have found to be an improvement.

Combine this with my favorite Obsidian search plugin Omnisearch and you end up making this bunch of random chat threads useful - now I can link and tag across, and source them for new ideas.

The Omnisearch plugin might be what you need. No AI but weighted results depending on where your query words are found (filename, titles, frequency...). It works well for me, it's my primary way to find notes.

The tag system works well for GTD workflows and organization in general. Default search isn't the best but the Omnisearch plugin fixes that.

Also - and speaking about plugins in general - the best way to get an issue resolved is to ask it on the GitHub page. If the plugin is maintained, its developer will usually gladly help you solve your problem :) https://github.com/scambier/obsidian-omnisearch/issues

I think Obsidian Omnisearch can help you with that.

The Omnisearch plug-in for Obsidian does search in PDFs and images via OCR.

In my opinion it is absolutely possible. The developer of the Omnisearch plugin now works on PDF indexing - https://github.com/scambier/obsidian-omnisearch/releases/tag/1.6.5-beta.3.
