[原创]openwebui解决searxng通过接口请求不成功问题

openwebui 对接 searxng 时 无法查询到联网信息，使用bing搜索，每次返回json是正常的

神秘代码：

http://172.30.254.200:8080/search?q=北京市天气&format=json&language=zh&time_range=&safesearch=0&language=zh&locale=zh-Hans-CN&autocomplete=&favicon_resolver=&image_proxy=0&method=POST&safesearch=0&theme=simple&results_on_new_tab=0&doi_resolver=oadoi.org&simple_style=auto&center_alignment=0&advanced_search=0&query_in_title=0&infinite_scroll=0&search_on_category_select=1&hotkeys=default&url_formatting=pretty&disabled_plugins=&enabled_plugins=&tokens=&categories=general&disabled_engines="wikipedia__general\054currency__general\054wikidata__general\054duckduckgo__general\054google__general\054lingva__general\054qwant__general\054startpage__general\054dictzone__general\054mymemory translated__general\054brave__general"&enabled_engines=bing__general

官方教程是这样设置的  非常不稳定，经常搜索不到结果

        query (str): The search term or question to find in the SearXNG database.

 改完 看到请求参数

总结   openwebui 对接SearXNG 有bug 我修不来 ，提出的关键词就会被修改掉为什么呢？

接着搞，把搜索关键字写死

 出结果了

 实际搜索到网页是正确的，结果就 是不行，是模型问题还是openwebui问题？

搞不来了，放弃
