See below. If there’s only one search result I’d like enter work the same way as clicking the first result.
Im also interested in this feature, if you figure out a way please let me know 
Hello @GB44 and @simon.w.jones,
You can do a search by pressing enter but in a different way. You need to place an input element instead of a search element and place a search button after the input element.
Note (Install Search & Autocorrect Plugin | Bubble).
Create a custom state in which your input value will get saved.
After that start a workflow on the search button. Set the value for the custom state as shown in the screenshot.
Next, you have to set the condition for the repeating group to search for the specific data the user has input. (As shown in the screenshot).
If any further assistance is required please contact me on:
