Description Arguments Details Examples
An R6 class to control the gathering, sorting and paging of search results. This
class controls a number of SearchSource
instances by instantiating them,
and triggering new searches. Results are merged together and stored in the
controller, with pages returned as needed.
sources |
a named list of sources. Each source must be a list containing
at least |
$new(sources = NULL)
starts a new search controller
$set_sources(sources)
If sources is provided they are concatenated they are
retrieved from rcloud.config
(main_source
)
and .session
(gist_sources
).
$search(all_sources, start, pagesize, sortby, orderby, ...)
Main search interface. Arguments match rcloud.search
. If start is
not zero it will read from internal cache, otherwise it will call new_search
.
$new_search(all_sources, sortby, orderby, ...)
This triggers a search on the sources and merges/sorts the results back together into
the results
internal object.
$build_response(start, pagesize)
Build the response to send back to RCloud. This takes the start point and page size and
returns the right page from the results.
$get_sources()
return the config
$get_raw_results()
return the results as returned by sources
$get_results()
return the merged results
