What is your question?

I add to my project in Milvus search a filter with "TEXT_MATCH(page,content, '{word}')" for word in key
But when I try to search for a specific word returns entites that dont have the word.

# Define search parameters
search_params = {"metric_type": "COSINE", "params": {"nprobe": 50}}
top_k = 20

# Define filter parameters
key = get_keywords(query_text)
filter_parms = " or ".join([f"TEXT_MATCH(page_content, '{word}')" for word in key])
print(filter_parms)

return collection.search(
    data=query_embedding,
    anns_field="embeddings",
    #partition_names=[particion_post_name,particion_opi_name],
    partition_names=[particion_post_name],
    filter=filter_parms,
    param=search_params,
    limit=top_k,
    output_fields=["metadata", "page_content"],
)

Anything else?
