where is the prompt template that I can edit for when I call `query` on a query engine?

Please stand by @ryanglambert as I search the knowledge base. We are experiencing especially high traffic right now and might take longer than usual. :wave:

----------------------
To edit the prompt template when calling query on a query engine, you need to customize the prompt based on the index you are using. Here are the prompt templates for different indices:

1. For GPTEmptyIndex:
   
   • input_prompt: A Simple Input Prompt (see Prompt Templates (https://gpt-index.readthedocs.io/en/latest/reference/prompts.html#prompt-templates)).
   Source: Querying an Empty Index (https://gpt-index.readthedocs.io/en/latest/reference/indices/empty_query.html)

1. For GPTTreeIndex:
   
   • query_template: Tree Select Query Prompt (see Prompt Templates (https://gpt-index.readthedocs.io/en/latest/reference/prompts.html#prompt-templates)).
   • query_template_multiple: Tree Select Query Prompt (Multiple) (see Prompt Templates (https://gpt-index.readthedocs.io/en/latest/reference/prompts.html#prompt-templates)).
   • text_qa_template: Question-Answer Prompt (see Prompt Templates (https://gpt-index.readthedocs.io/en/latest/reference/prompts.html#prompt-templates)).
   • refine_template: Refinement Prompt (see Prompt Templates (https://gpt-index.readthedocs.io/en/latest/reference/prompts.html#prompt-templates)).
   Source: Querying a Tree Index (https://gpt-index.readthedocs.io/en/latest/reference/indices/tree_query.html)

1. For GPTKeywordTableIndex:
   
   • keyword_extract_template: Keyword Extract Prompt (see Prompt Templates (https://gpt-index.readthedocs.io/en/latest/reference/prompts.html#prompt-templates)).
   • query_keyword_extract_template: Query Keyword Extract Prompt (see Prompt Templates (https://gpt-index.readthedocs.io/en/latest/reference/prompts.html#prompt-templates)).
   Source: Querying a Keyword Table Index (https://gpt-index.readthedocs.io/en/latest/reference/indices/table_query.html)

1. For GPTKGTableIndex:
   
   • query_keyword_extract_template: Query Keyword Extract Prompt (see Prompt Templates (https://gpt-index.readthedocs.io/en/latest/reference/prompts.html#prompt-templates)).
   Source: Querying a Knowledge Graph Index (https://gpt-index.readthedocs.io/en/latest/reference/indices/kg_query.html)

You can customize these prompt templates according to your needs. For more details on customizing prompts, refer to the Custom Prompts How-To (https://gpt-index.readthedocs.io/en/latest/how_to/customization/custom_prompts.html) guide.

Lol do you want the location in the codebase of the existing prompt templates?

Usually you'll want to customize both the text_qa_template and refine_template

❤️ you da man!

I'm using ComposableGraph.from_indices(GPTListIndex, ...

Does your advice still apply then?

Where do you put the text_qa_template and refine_template thing?

@kapa.ai where do we put text_qa_template and refine_template when we use ComposableGraph?

Let me check the knowledge base for you. One moment! :books:

----------------------
Hmm, I don't know enough to give you a confident answer yet. However, you can refer to the GPT index documentation for more information on customization and usage: GPT index documentation (https://gpt-index.readthedocs.io/en/latest/).

You'll put that in the custom query engines for each index 👍

For reference the default templates are here:

And if you are using gpt-3.5, there are specific prompts here (it only has a specific refine template. The other text_qa_template is converted into a single human message for gpt-3.5)
