Hope this helps - is only a special character in character classes [...]
Your problem comes from v -12.1892 -53.4267 -276.4055 containing 2 spaces in between v and -12.18.... Your regex only matches one.
code :
^(\w+)\s*((\S+)( \S+)*) *$
^(\w+)(\s*\S+)*$

Does that help You need to escape the minus sign because - is a special character.
Try (\+|\-)? (note the backslash).

it fixes the issue In case your field has a sub field with keyword type in it use (field1.field3.keyword):
code :
{
"query": {
        "bool": {
            "must": [
                {
                    "match": { "field1:field2" : "Complete" }
                },
                {
                    "bool": {
                        "should": [
                            {
                                "regexp": { "field1.field3.keyword" : ".*mysource_.+20190102" }
                            }
                        ]
                    }
                }
            ]
        }
    },
    "size":10000
}
