Feature Request: Add SEARCH_QUERY_GENERATION_PROMPT_TEMPLATE for safer and more relevant web search prompts

[flefevre]

Description

Currently, the project includes the QUERY_GENERATION_PROMPT_TEMPLATE parameter to control how general prompts are generated.
However, there is no dedicated configuration for web search–specific prompts.

Proposal

Add two new configuration parameters:

• SEARCH_QUERY_GENERATION_PROMPT_TEMPLATE
  → Allows defining a custom prompt template specifically for internet search queries.
  This enables more precise and context-aware search generation.

• DEFAULT_SEARCH_QUERY_GENERATION_PROMPT_TEMPLATE
  → Provides a default fallback template for web search prompts if no custom one is defined.

Motivation

• Improve the relevance and safety of search-related prompts.
• Prevent unintended data leaks by better controlling which context is included in web queries.
• Enable developers and deployers to fine-tune search behavior independently from general query generation.

Example

# New parameters
SEARCH_QUERY_GENERATION_PROMPT_TEMPLATE="Generate a concise web search query based on the user request, excluding any private or local context."
DEFAULT_SEARCH_QUERY_GENERATION_PROMPT_TEMPLATE="Generate a general web search query for the given topic."

Expected Impact

• More specific and secure query generation for web-based searches.
• Better alignment between general LLM prompts and external information retrieval logic.

Thanks

I like it, but do not introduce two new parameters - only once.
Just SEARCH_QUERY_GENERATION_PROMPT_TEMPLATE which is filled, by default, with a default value (fallback).
And user can overwrite it in env or via UI.

No need to have two separate env vars.

And I like it because this way, you can have more powerful web searches which utilize conditional search parameters while still having natural sounding queries for RAG in a separate generation prompt

Ok perfect. I was proposing two because I have noticed their were also two for other cases.

You confirm me that ENABLE_SEARCH_QUERY_GENERATION = false , deactivate all generation for web search, only the initial prompt will be send to searching for instance. No additional contexte.
