Searching for Group Member

Feature Description
Only locally stored group members can be searched for, such as the list of group members or group member profiles that have been pulled.
Note: 
This feature cannot be used for audio-video groups (AVChatRoom) as the group members are not stored locally.
Searching a Local Group
Call the GroupSearchGroupMembers API (Details) to search for a local group member.
You can set the search keyword group_search_member_params_keyword_list and specify the search scope to set whether to search by the memberUserID, memberNickName, memberRemark, and memberNameCard fields of a group member.
Depending on whether group_search_member_params_groupid_list of the GroupMemberSearchParam (Details) in GroupSearchGroupMembers is empty (null), there are two cases:
If group_search_member_params_groupid_list is left empty, members in all the groups will be searched for and returned by groupID.
If group_search_member_params_groupid_list is not left empty, members in the specified group will be searched for.
Sample code:
// Search for group members by the keyword and group ID
GroupMemberSearchParam param = new GroupMemberSearchParam
{
  group_search_member_params_groupid_list = new List<string>
  {
    "group_id"
  },
  group_search_member_params_keyword_list = new List<string>
  {
    "Keyword 1"
  },
  group_search_member_params_field_list = new List<TIMGroupMemberSearchFieldKey>
  {
    TIMGroupMemberSearchFieldKey.kTIMGroupMemberSearchFieldKey_Identifier,
    TIMGroupMemberSearchFieldKey.kTIMGroupMemberSearchFieldKey_NikeName,
    TIMGroupMemberSearchFieldKey.kTIMGroupMemberSearchFieldKey_Remark,
    TIMGroupMemberSearchFieldKey.kTIMGroupMemberSearchFieldKey_NameCard,
  }
};
TIMResult res = TencentIMSDK.GroupSearchGroupMembers(param, (int code, string desc, List<GroupGetOnlineMemberCountResult> result, string user_data)=>{
 // Process the async logic
});
