# Searching on an ad-hoc value set

For this example we assume THO and SNOMED International are loaded.

We'll search now based on two property filters:

- `370135005 | pathological process` = `441862004 | Infectious process`
- `363698007 | findign site` = `113255004 | lung`
- and the text `fever`

```http
