By default, searches are case-insensitive. You can make your search
case-sensitive by using the [`case`](https://developers.google.com/code-search/reference#filters) filter.

For example, the following search returns only results that match the term
`HelloWorld`. It excludes results where the case doesn't match, such as
`helloWorld` or `helloworld`.
