# Query string

You can use a URL match in combination with a funnel to match URLs which contain query string params. In this example we are going to explore how to match against the following URL:
`/product?category=parachutes`

## 1. Define a URL match

First we are going to match the path portion of the URL with the following URL match: `/product`.

See the [URL match docs](/docs/url-match/) for more information.

## 2. Add a funnel

While the URL match will correctly match `/product?category=parachutes` it will also match other unwanted URLs like no query string params `/product` or the wrong query string params `/product?category=bananas` etc. To fix this we are going to add a funnel directly after the URL match to restrict the query string params that we accept.

`Param Key` = `category`
`Param Value` = `parachutes`

If you have multiple query string params that you want to match against you can add another by clicking the `+ ADD` button.
