i am trying to learn the Spacy’s Matcher class for pattern matching.

when i am trying to match the word “solar” in the sentence it is not matching. Even though there are multiple solar words that are present.

here is the pattern: pattern1 = [[{"LOWER":"SOLAR"}]]

i added to te matcher: matcher.add("solar", pattern1)

doc : nlp('solar Solarpowered energy runs solar solar-powered cars solar .')

even though there are multiple solar words in the sentence it is not getting identified.

for match_id, start, end in matches:
    matched_pattern = nlp.vocab.strings[match_id]
    text =doc[start:end]
    print(text.text, start, end, matched_pattern)

I am getting empty result it is not identifying anyg solar word.

i tried multiple patterns but nothing worked to identify single word “Solar”. It can able to identify solar power but not just solar. Can anyone help me here.
