!pip install llama-index pymongo
from llama_index.core import SummaryIndex
from llama_index.readers.mongodb import SimpleMongoReader
from IPython.display import Markdown, display
import os
host = "<host>"
port = "<port>"
db_name = "<db_name>"
collection_name = "<collection_name>"
# query_dict is passed into db.collection.find()
query_dict = {}
field_names = ["text"]
reader = SimpleMongoReader(host, port)
documents = reader.load_data(
    db_name, collection_name, field_names, query_dict=query_dict
index = SummaryIndex.from_documents(documents)
# set Logging to DEBUG for more detailed outputs
query_engine = index.as_query_engine()
response = query_engine.query("<query_text>")
