#' Hansard Database
#'
#' This database contains information on matters discussed in Council meeting
#' since the fifth term of LegCo. Hinting by its name, the database is built
#' upon the PDF hansard files. Relying on the bookmarks and section codes of the
#' hansard files, the data endpoints retrieve data from the files directly.

#'   \code{NULL}, returns results of all hansard files. Defaults to \code{NULL}.
#'

#'   of ids. If \code{NULL}, returns all speakers. Defaults to \code{NULL}.

#'
#' @param from only fetch results of meetings on or after this date. Accepts
#'   character values in \code{"YYYY-MM-DD"} format, and objects of class
#'   \code{Date}, \code{POSIXt}, \code{POSIXct}, \code{POSIXlt} or anything else
#'   that can be coerced to a date with \code{as.Date()}. Defaults to
#'   \code{"1900-01-01"}.
#'
#' @param to only fetch results of meetings on or before this date. Accepts
#'   character values in \code{"YYYY-MM-DD"} format, and objects of class
#'   \code{Date}, \code{POSIXt}, \code{POSIXct}, \code{POSIXlt} or anything else
#'   that can be coerced to a date with \code{as.Date()}. Defaults to the
#'   current system date.
#'
#' @param floor logical: whether to fetch results from the floor version of the
#'   hansard files? The floor version is the first presented version of hansard
#'   file in the original language delivered by the speakers in LegCo. If
#'   \code{TRUE}, the language option is ignored. Defaults to \code{FALSE}.

#'
#' @param extra_param additional query parameters defined in LegCo API. Must
#'   begin with \code{"&"}.
#'
#' @param n the number of record to fetch. Defaults to \code{1000}.
#'
#' @param count logical: Whether to return only the total count of records that
#'   matches the parameter(s) instead of the result. Defaults to \code{FALSE}.
#'
#' @param verbose logical: Whether to display progress messages when fetching
#'   data? Defaults to \code{TRUE}.

#' Complementary Functions
#'
#' This set of complementary functions are wrappers around the database
#' functions that facilitate the use of the LegCo API or return data from the
#' API in a more usable form. All complementary functions have a prefix of
#' \code{search_}.
#'
#' @section Functions: Complementary Functions: \itemize{ \item
#'   \code{\link{search_committee}}: Search LegCo committees \item
#'   \code{\link{search_member}}: Search LegCo members \item
#'   \code{\link{search_voting_record}}: Search Voting Record in LegCo meetings
#'   \item \code{\link{search_question}}: Search full text of question put to
#'   the government by LegCo members}
#'
#' @section Notes: The complementary functions work by calling a number of
#'   database functions and combining their output, meaning that a function call
#'   usually involves multiple API calls. Use with caution to prevent reaching
#'   the API’s rate limit too quickly.
