Feature Request: Add serpbase.dev as a Google search backend alongside SearXNG

[gefsikatsinelou]

Hi @yokingma,

SearChat is an impressive project — the DeepResearch support and the clean Docker deployment make it one of the more accessible self-hosted AI search engines, especially for Chinese-speaking users.

Pain point with the current search setup
I noticed SearChat currently uses SearXNG as the search backend. SearXNG is excellent for privacy and multi-engine aggregation, but in practice I've found that its Google results can be inconsistent:

• CAPTCHA blocks on some SearXNG instances, especially those hosted on cloud IPs.
• Rate limiting that causes empty result sets during peak usage.
• Occasional formatting changes on Google's side that break the scraping pipeline temporarily.

For users who need reliable, high-volume Google search specifically, this creates a reliability gap.

Suggestion
Would you consider adding https://serpbase.dev as an optional dedicated Google search backend? It's a Google Search Results API that returns clean, structured JSON (title, URL, snippet, rich results) without the scraping overhead. Users could choose:

• search_provider: "searxng" for privacy-focused multi-engine aggregation.
• search_provider: "serpbase" for stable, high-quality Google results when SearXNG's Google source is unreliable.

Why it complements SearChat

• It doesn't replace SearXNG; it gives users a choice based on their priority (privacy vs. Google result stability).
• The API is priced for developers, which fits SearChat's self-hosted audience.
• Response structure is simple JSON, so integration into the existing search pipeline should be minimal.

I'm happy to help test the integration or provide sample code for the provider module.
