Instead of wrapping the search term with `\<...\>`, enable the
`WHOLE_WORD` search option.
The advantage of the search option is that it can be toggled with one
click/key press (alt+w by default), and it doesn't require regex mode.
Release Notes:
- Vim mode's whole word search now uses the search bar's "Match whole
words" option, instead of wrapping the search term with `\<...\>`. This
allows easier toggling of whole-word search, and it also works without
enabling the regex mode.
