Implementation of a global search for chats in telegram tdlib

Question

I'm trying to replicate the global chat search as in telegram.

I'm using getChats method for searching, but the problem is that the method only returns a list of ids.

In addition to the id, I would also like to get the name and avatar of the chat.

Therefore, I have to go through the chatids in the forEach and for each id call the getChat method that returns the data I need. This, in turn, causes severe problems with the query execution time. (14 seconds). In a telegram, the search takes ~2 seconds. I don't know how they did it, I re-read all the documentation and did not find a method that would allow me to pass the name of the chat and get, in addition to identifiers, also a title and an image. Has anyone already encountered a similar problem?

import BaseAction from "./BaseAction";
import airgram from "../airgram/airgram";
import { ChatsUnion, ChatUnion } from 'airgram';

class SearchChatsAction implements BaseAction
{
    async run(name: string): Promise<any>
    {
        const output = await airgram.api.searchPublicChats({
            query: name
        });

        const promises: Array<any> = [];
        const result: Array<any> = [];
        for (const chatId of (output.response as ChatsUnion).chatIds)
        {
            promises.push(
                airgram.api.getChat({
                    chatId: chatId
                }).then(output => {
                    result.push({
                        id: (output.response as ChatUnion).id,
                        title: (output.response as ChatUnion).title
                    });
                })
            );
        }

        await Promise.all(promises);
        return result;
    }
}

export default SearchChatsAction;

I think the issue you're facing is because of API. You should try using different API. If you check these two documentations:

1. searchPublicChat
2. searchPublicChats

The API you're using returns just chatIds but searchPublicChat will contain all the information of searched chat.
