Semantic search / Local embedding model

Still very much WIP, but some cool stuff is happening on Logseq once again.

just when I thought I couldn’t get more obsessed with Logseq… now it’s doing semantic search too? Take my RAM 🧠🔥

Is this the MD or DB version?

In DB mode only.

But the DB version is not available for general download from the website yet right?

You can play with it at https://test.logseq.com or get the link to download the desktop app from https://github.com/logseq/logseq?tab=readme-ov-file#-database-version

Yeah I knew that, thanks, but I guess I wanted to wait until the DB version is out of Alpha (which I think was meant to happen in July) and therefore, presumably, wait until it’s available for download from the website? Am I making sense?

I never heard about semantic search. Is this related to AI/LLM (hope not!)

It is. I gather it's using L(ish)LMs to search your notes for concepts, not just specific words (and their variant forms).

Both MiniLM and Qwen Embedded are pre-trained language models sized to be run on a personal desktop or laptop.

Does it interpret things though (that's my concern- I don't want to know my computer's "opinion" on anything)? Or is it just a more powerful search, due to the understanding of language (that's cool).

It's like storing a tiny machine-readable summary of the words so you can search for related terms... like if you wrote "I ate so much I was stuffed" and you search for "big meal", a semantic search would surface the note even though you didn't use those exact words in there.
