Search and Discovery App - Change to treat search terms with an 'OR' instead of 'AND'

[linia]

The search terms in my store are treated with an 'AND' operator by default.

I have a presentation templates shop.

So if a user searches for 'business risk' it currently returns 0 results, even though I have templates tagged 'risk,' because the search expects that all terms are found.

There is no setting to change the search from an 'AND' search to an 'OR' search.

Has anyone been able to update their code or theme/templates to allow the search to return results for *any* rather than *all* the search terms?

Any guidance would be much appreciated.
