### With citations

If you want to get the answer to question and return both answer and citations, use the following code snippet:

```python With Citations
from embedchain import Pipeline as App

# Initialize app
app = App()

# Add data source
app.add("https://www.forbes.com/profile/elon-musk")

# Get relevant answer for your query
answer, sources = app.query("What is the net worth of Elon?", citations=True)
print(answer)
# Answer: The net worth of Elon Musk is $221.9 billion.

print(sources)
# [
#    (
#        'Elon Musk PROFILEElon MuskCEO, Tesla$247.1B$2.3B (0.96%)Real Time Net Worthas of 12/7/23 ...',
#        'https://www.forbes.com/profile/elon-musk',
#        '4651b266--4aa78839fe97'
#    ),
#    (
#        '74% of the company, which is now called X.Wealth HistoryHOVER TO REVEAL NET WORTH BY YEARForbes ...',
#        'https://www.forbes.com/profile/elon-musk',
#        '4651b266--4aa78839fe97'
#    ),
#    (
#        'founded in 2002, is worth nearly $150 billion after a $750 million tender offer in June 2023 ...',
#        'https://www.forbes.com/profile/elon-musk',
#        '4651b266--4aa78839fe97'
#    )
# ]
```

<Note>
When `citations=True`, note that the returned `sources` are a list of tuples where each tuple has three elements (in the following order):
1. source chunk
2. link of the source document
3. document id (used for book keeping purposes)
</Note>

### Without citations

If you just want to return answers and don't want to return citations, you can use the following example:

```python Without Citations
from embedchain import Pipeline as App

# Initialize app
app = App()

# Add data source
app.add("https://www.forbes.com/profile/elon-musk")

# Get relevant answer for your query
answer = app.query("What is the net worth of Elon?")
print(answer)
# Answer: The net worth of Elon Musk is $221.9 billion.
