I have pre annotated with spacy with Entity Ruler for building a model in Prodigy but some of the patterns cannot be identified by the ruler.  
Ex: pattern = [{'label': 'A', 'pattern': [{'LOWER': 'PP'}]}]

It is seen that it didnot find the entity? what's the reason behind it? I have used below lines for the ruler:

nlp = spacy.blank("en")  
ruler = nlp.add\_pipe('entity\_ruler')  
ruler.add\_patterns(pattern)

Hi @ta13,

I am curious as to what recipe are you using for pre-annotation? If it's `ner.correct` + a model saved with the entity ruler, then it should work because the entities are in `doc.ents`.

Perhaps you can try using the `--patterns` argument, it takes the same format as the EntityRuler and will highlight all matches.
