Put these keywords separated by comma. ***Caution:*** Filteration might slow down the automation and use higher automation resourse from your account. But it is recommended to use filters to avoid bad profies. Language filteration is not recommended. Because as an example, a german user might have a profile with English bio, so if you set the language to German only, you will be missing that profile as a target! But if you focus to have profile for specific languages only, you are good to use this function. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://faq.botrush.ai/guides/username-and-full-name-blacklist-and-language-filtration.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
