I have a collection named Docs in the qdrant database. There are multiple points in this collection. Each point has metadata including the title of the document. I want to extract a list of titles. I tried to do it but it returned none. How can I do it?

from qdrant_client import QdrantClient, models

client = QdrantClient(url="http://localhost:6333")

result = client.scroll(
    collection_name="Docs",
    scroll_filter=models.Filter(
        must=[
            models.FieldCondition(
                key="meta.title",
                match=models.MatchText(text='*')
            )
        ]
    )
)

result
