Description

Given the text:
"Kontraktsproget vil være dansk og arbejdssproget kan være dansk, svensk, norsk og engelsk"
and the query:
{!complexphrase df=content_da}("sve* no*")
the unified highlighter (hl.method=unified) does not return any highlights.

For reference, the original highlighter returns a snippet with the expected highlights:
Kontraktsproget vil være dansk og arbejdssproget kan være dansk, <em>svensk</em>, <em>norsk</em> og

Is this expected behaviour with the unified highlighter?
