      ConversationSearch is mainly used to search the conversation list, consisting of ConversationSearchInput and ConversationSearchResult.

      Basic Usage

      Used in ConversationList
      Used independently
      import { UIKitProvider, ConversationList, ConversationSearch, IConversationSearchProps } from '@tencentcloud/chat-uikit-react';
      import { IConversationModel } from '@tencentcloud/chat-uikit-engine';
      
      const CustomConversationSearch = (props: IConversationSearchProps) => {
        const onSelectResult = (conversation: IConversationModel) => {
          console.warn(`Select Search Result: ${conversation.conversationID}`);
        };
        return (
          <ConversationSearch {...props} onSelectResult={onSelectResult} />
        );
      };
      
      const App = () => {
        return (
          <UIKitProvider>
            <ConversationList
              style={{ maxWidth: '300px', height: '600px' }}
              ConversationSearch={CustomConversationSearch}
             />
           </UIKitProvider>
        );
      };
      import { UIKitProvider, ConversationListProvider, useConversationList, ConversationSearch } from '@tencentcloud/chat-uikit-react';


      const CustomConversationSearch = () => {
        const { conversationList } = useConversationList();
        return (
          <ConversationSearch
            style={{ maxWidth: '300px', maxHeight: '500px' }}
            conversationList={conversationList}
          />
        );
      };
      
      const App = () => {
        return (
          <UIKitProvider>
            <ConversationListProvider>
              <CustomConversationSearch />
            </ConversationListProvider>
          </UIKitProvider>
        );
      };

      Search rules

      Default search rules

      When searchFn is not provided, searchFn will use the default value defaultSearchFn as the search rule.
      defaultSearchFn defaults to searching and matching the conversation title in the conversation list, case insensitive. defaultSearchFn Definition is as follows:
      function defaultSearchFn(searchValue: string, conversationList: IConversationModel[]) {
        if (!searchValue || conversationList?.length === 0) return [];
        return conversationList.filter(item => item.getShowName().toLocaleLowerCase().includes(searchValue.toLocaleLowerCase()));
      }

      Custom Search Rules

      You can implement different search rules by passing searchFn props. Here is an example of searching based on conversationID information in the conversation list:
      function customSearchFn(searchValue: string, conversationList: IConversationModel[]) {
        if (!searchValue || conversationList?.length === 0) return [];
        return conversationList.filter(item => item.conversationID.includes(searchValue));
      }
      
      <ConversationSearch {...props} searchFn={customSearchFn} />

      Event Handling

      ConversationSearch provides a rich set of props to help you customize responses to various search states.
      onSearchChange is called when the search input changes.
      onFocus is called when the search input gains focus.
      onBlur is called when the search input gains focus.
      onSelectResult is called when a search result is selected.
