+### Search across Different Languages
+  To search for notes in multiple, different languages, you can use a [multi-lingual model](https://www.sbert.net/docs/pretrained_models.html#multi-lingual-models).<br />
+  For example, the [paraphrase-multilingual-MiniLM-L12-v2](https://huggingface.co/sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2) supports [50+ languages](https://www.sbert.net/docs/pretrained_models.html#:~:text=we%20used%20the%20following%2050%2B%20languages), has good search quality and speed. To use it:
+  1. Manually update `search-type > asymmetric > encoder` to `sentence-transformer/paraphrase-multilingual-MiniLM-L12-v2` in your `~/.khoj/khoj.yml` file for now. See diff of `khoj.yml` below for illustration:
+  ```diff
+   asymmetric:
+- encoder: "sentence-transformers/multi-qa-MiniLM-L6-cos-vi"
++ encoder: "sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2"
+     cross-encoder: "cross-encoder/ms-marco-MiniLM-L-6-v2"
+     model_directory: "~/.khoj/search/asymmetric/"
+  ```
+
+  2. Regenerate your content index. For example, by opening [\<khoj-url\>/api/update?t=force](http://localhost:8000/api/update?t=force)
