hello guys i m using Mongodb to store

the LLM decided it couldn't get the information. Maybe the source information or query was to vague

for example in the documets that i have there is a lot articles and for example when i ask a question about a article with his number it says there is no article with this number but when i check the sources that gave the answer the document that i asked about is there @Logan M

@Logan M @dev_advocate what is the recommended value of similarity_top_k i dont know what is the problem

It very much depends on the data and query types, you can find the optimal value for your usecase via trial and error

Also for your query type (finding article with a number) vector searc doesn't do well

Try with metadata filters

@Rohan thank u very much is there any documentation about metadata filters ?

Yes https://docs.llamaindex.ai/en/stable/module_guides/indexing/metadata_extraction/

thanks
