Hi,
It's a bug in MLTComponent, it can't handle field values with colon, etc.
As a workaround we can use [subquery] result transformer with mlt query
parser.
For example, in Solr admin UI
I added fl param as fl=workaround:[subquery], then in raw parameters:
workaround.q={!mlt qf=manu v=$row.id mintf=0 mindf=0}
This query adds subquery result into every doc like:
"workaround":{"numFound":2,"start":0,"numFoundExact":true,"docs":[ { "id":
"VS1GB400C3",
