I came across a question (QGIS algorithm parameter: ParameterString, question 1) which might be a duplicate of another one (QGIS Processing - Additional Creation Parameter for GdalWarp, question 2). I was about to flag it, but I can't find question 2 in the list of suggested duplicates, even with the full title or keywords from the title (qgis/gdalwarp/parameter/...):
This is not the first time I face this issue. I guess this is a bug; is there a known workaround?
This is the placeholder implying that simple search is possible:
As Andre Silva noted, question 2 (older question) shouldn't be able to be selected anyway since it has not been answered (no positive score or accepted answer). So, it's kind of a bad example... However, the error message "Your search returned no matches; please try a different search" implies that this constraint is not the source of the issue.
