+## Callout support
+
+Quartz supports the same Admonition-callout syntax as Obsidian.
+
+This includes
+- 12 Distinct callout types (each with several aliases)
+- Collapsable callouts
+
+See [documentation on supported types and syntax here](https://help.obsidian.md/How+to/Use+callouts#Types).

+title: "Hosting with Docker"
+tags:
+- setup
+---
+
+If you want to host Quartz on a machine without using a webpage hosting service, it may be easier to [install Docker Compose](https://docs.docker.com/compose/install/) and follow the instructions below than to [install Quartz's dependencies manually](notes/preview%20changes.md).
+## Hosting Quartz Locally
+You can serve Quartz locally at `http://localhost:1313` with the following script, replacing `/path/to/quartz` with the 
+actual path to your Quartz folder.
+
+docker-compose.yml
+```
+services:
+  quartz-hugo:
+    image: ghcr.io/jackyzha0/quartz:hugo
+    container_name: quartz-hugo
+    volumes:
+      - /path/to/quartz:/quartz
+    ports:
+      - 1313:1313
+
+    # optional
+    environment:
+      - HUGO_BIND=0.0.0.0
+      - HUGO_BASEURL=http://localhost
+      - HUGO_PORT=1313
+      - HUGO_APPENDPORT=true
+      - HUGO_LIVERELOADPORT=-1
+```
+
+Then run with: `docker-compose up -d` in the same directory as your `docker-compose.yml` file.
+
+While the container is running, you can update the `quartz` fork with: `docker exec -it quartz-hugo make update`.
+
+## Exposing Your Container to the Internet
+
+### To Your Public IP Address with Port Forwarding (insecure)
+
+Assuming you are already familiar with [port forwarding](https://en.wikipedia.org/wiki/Port_forwarding) and [setting it up with your router model](https://portforward.com):
+
+1. You should set the environment variable `HUGO_BASEURL=http://your-public-ip` and then start your container.
+2. Set up port forwarding on your router from port `p` to `your-local-ip:1313`.
+3. You should now be able to access Quartz from outside your local network at `http://your-public-ip:p`.
+
+However, your HTTP connection will be unencrypted and **this method is not secure**.
+
+### To a Domain using Cloudflare Proxy
+
+1. Port forward 443 (HTTPS) from your machine.
+2. Buy a custom domain (say, `your-domain.com`) from [Cloudflare](https://www.cloudflare.com/products/registrar/). Point a DNS A record from `your-domain.com` to your public IP address and enable the proxy.
+3. Set the environment variables `HUGO_BASEURL=https://your-domain.com`, `HUGO_PORT=443`, and `HUGO_APPENDPORT=false`. Change `1313:1313` to `443:443` for the `ports` in `docker-compose.yml`.
+4. Spin up your Quartz container and enjoy it at `https://your-domain.com`!
+
+### To a Domain using a Reverse Proxy
+
+If you want to serve more than just Quartz to the internet on this machine (or don't want to use the Cloudflare registrar and proxy), you should follow the steps in the section above (as appropriate) and also set up a reverse proxy, like [Traefik](https://doc.traefik.io/traefik). Be sure to configure your TLS certificates too!

+title: "Search"
+---
+
+Quartz supports two modes of searching through content.
+
+## Full-text
+Full-text search is the default in Quartz. It produces results that *exactly* match the search query. This is easier to setup but usually produces lower quality matches.
+
+```yaml {title="data/config.yaml"}
+# the default option
+enableSemanticSearch: false
+```
+
+## Natural Language
+Natural language search is powered by [Operand](https://beta.operand.ai/). It understands language like a person does and finds results that best match user intent. In this sense, it is closer to how Google Search works.
+
+Natural language search tends to produce higher quality results than full-text search.
+
+Here's how to set it up.
+
+1. Login or Register for a new Operand account. Click the verification link sent to your email, and you'll be redirected to the dashboard. (Note) You do not need to enter a credit card to create an account, or get started with the Operand API. The first $10 of usage each month is free. To learn more, see pricing. If you go over your free quota, we'll (politely) reach out and ask you to configure billing.
+2. Create your first index. On the dashboard, under "Indexes", enter the name and description of your index, and click "Create Index". Note down the ID of the index (obtained by clicking on the index name in the list of indexes), as you'll need it in the next step. IDs are unique to each index, and look something like `uqv1duxxbdxu`.
+3. Click into the index you've created. Under "Index Something", select "SITEMAP" from the dropdown and click "Add Source".
+4. For the "Sitemap.xml URL", put your deployed site's base URL followed by `sitemap.xml`. For example, for `quartz.jzhao.xyz`, put `https://quartz.jzhao.xyz/sitemap.xml`. Leave the URL Regex empty. 
+5. Get your API key. On the dashboard, under "API Keys", you can manage your API keys. If you don't already have an API key, click "Create API Key". You'll need this for the next step.
+6. Open `data/config.yaml`. Set `enableSemanticSearch` to `true`, `operandApiKey` to your copied key, and `operandIndexId` to the ID of the index we created from earlier..
+
+```yaml {title="data/config.yaml"}
+# the default option
+search:
+  enableSemanticSearch: true
+  operandApiKey: "jp9k5hudse2a828z98kxd6z3payi8u90rnjf"
+  operandIndexId: "s0kf3bd6tldw"
+```
+7. Push your changes to the site and wait for it to deploy.
+8. Check the Operand dashboard and wait for your site to index. Enjoy natural language search powered by Operand!
