As someone who works in information retrieval, I've always felt search in the Obsidian ecosystem was lacking. So I built **Seek**: a hybrid (semantic + keyword) search plugin built exclusively for Obsidian vault search. I focused primarily on relevance, ease of use, and speed. 

  
**Features**

* Seek runs entirely inside Obsidian, no APIs, no local server. Once the model downloads to your device, everything stays local and within Obsidian.
* No configuration required. Seek is highly relevant out of the box and does not need to be dialed in. But, some customization is available for those who want it.
* Inline filtering with suggestions as you type, and easy to use keyboard shortcuts to get you to your results quickly. 
   * Seek follows the native search filtering syntax, making filtering on custom properties, tags, etc natural and easy.
* Edits and new notes index in near real time, even on mobile. The index also syncs across devices, so anything indexed on desktop shows up in phone search and vice versa.
   * *I don't recommend a full reindex on mobile though, it'll work, but drains your battery.*
* Massive vaults are no problem. I've tested Seek on 20k+ note vaults and search stayed well under 100ms. 
* Supports 52+ languages plus code (JS, C, Python, etc.), no configuration required.
* CLI & URL scheme for headless, scripted, or agentic usage.

**Relevance & Evaluation**

I spent weeks testing and iterating on the recall and ranking system on both public data sets, as well as annotated evals from logs of my own search usage in Obsidian. 

I've benchmarked Seek against Omnisearch and Smart Connections' smart lookup, both on public IR benchmarks and my own vault. I have a full write up on the relevance & evaluation strategy on [my blog if anyone is interested here](https://publish.obsidian.md/rmm/Seek+Documentation/Seek+Evaluation+%26+Development). 

Otherwise, here's a quick sample across a few data sets:

|Benchmark|Seek|Omnisearch|Smart Lookup|
|:-|:-|:-|:-|
|MLQA, English Q&A (600)|**0.625**|0.016|0.603|
|MIRACL, non-English avg|**0.555**|0.023|0.066|
|My vault's eval set (483)|**0.876**|0.811|0.670|
