This really doesn't seem necessary. What is your actual field
definition? I also think your cut/paste is messed up, this is wrong:
bdeut_nullablevaluebdeutnullablevaluebdeutnullablevalue
the vertical bars in the admin/analysis page are quite important here.
Either the cut/paste is doing weird thin
indexed term: bdeut_NullableValue
query term 1 : bdeut_nullablevalue (lowercase)
query term 2 : nullablevalue (lowercase)
current field type definition in order:
Whitespace Tokenizer
Word Delimiter Filter
Lowercase filter
current analysis output: [INDEX]schema_field
WT
text
bdeut_NullableValue
