I got this query:

let seriesQuery = seriesRepository.createQueryBuilder("series");
seriesQuery = seriesQuery
.select([
"series.programTitle",
"series.seriesTitle",
])

run as written, it would return say 100 times "game of thrones .. "

then I can say, seriesQuery = seriesQuery.distinctOn(["series.seriesTitle"])

but this distinct on would in this case apply only to entries who have a seriesTitle

and it would not apply to entries that have only a programTitle

A rudimentary solution would be to run two different queries and to glue their result into a one API call

is it possible to do it?
