NLP SPACY Matcher

[Alexo47]

Hello!

I am trying to analyze a text containing predefined names.
I created a doc = nlp(" my textmentioned above")
I created also a pattern (dictionary) with TEXT as pattern keys.
pattern_periods = [{"TEXT": "Summer 43"},...]
I added these pattern (discretionary) to the matcher.
matcher.add("roman_periods", [pattern_periods])
But when I lauch the matcher:
matches = matcher(doc)
No matches are found.

=> What am I missing?
