Search Function hangs/throws error

[fusionetics-cecelia]

Describe the bug
When using the search function, if a search term is entered and then the 'Enter' key is pressed, the console throws a Type error and the search hangs. This doesn't seem to happen if you simply type the search term and then wait for results to appear without hitting 'Enter'. This occurs on the wiki.js documentation page as well.

To Reproduce
Steps to reproduce the behavior:

1. Go to wiki homepage
2. Click on search bar and type in a term then press the 'Enter' key
3. See error

Search results to appear regardless of whether user hits the 'Enter' key
