# Filters

**Filters can made selection over stores.**

Filters allow you to narrow down selections across various stores. By
using filters, you can select participants, quizzes, and
responses. The command triggers a Text User Interface (TUI) that runs
a jq filter, displaying the outcome in real-time. After you're content
with the filtered JSON, pressing ⏎ will present the result on
stdout, enabling you to further process it by piping it forward.

## Examples

Filter over participants store.

**probo filter participants**

Filter over quizzes store using the jq filter in tags.jq file

**probo filter quizzes -i data/filters/tags.jq**

Filter over participants and pipe the result on the next filter. The result is then stored in a JSON file.

**probo filter participants | probo filter quizzes > data/json/selection.json**
