  relevant file	pr_agent/tools/pr_similar_issue.py
  suggestion	Consider refactoring the code to avoid duplication. The code for Pinecone and LanceDB is very similar, and it might be beneficial to extract the common parts into separate methods or classes. [important]
  relevant line	elif get_settings().config.vectordb == "lancedb":

  relevant file	pr_agent/tools/pr_similar_issue.py
  suggestion	It is recommended to handle exceptions more specifically rather than using a broad 'except' clause. This will help in identifying and handling different error scenarios appropriately. [important]

Hi @PrashantDixit0 . i gave some code comments, but in addition:

1. update https://github.com/PrashantDixit0/pr-agent/blob/main/docs/SIMILAR_ISSUE.md with an explanation of the different databases, and how to switch between them

2. I ran the tool on Integration with other vectorDbs [enhancement] #496, and got no similar issues. With vectordb=pinecone I did get suggestions. How do you know the tool works ? i do expect to get similar issues on this.

If there is a threshold to be set, make it configurable. but you must demonstrate that the tool indeed works, and can retrieve reasonable similar issues

3. change all print statements to get_logger.info(...)

Sure @mrT23, I'll work on your comments
