== search ==
Service performs searches for various information in ADEI and source databases.

=== Format of search string ===
The search string consists of four components:
 * The first component defines type of the search. Examples are ''item search'', ''channel value search'', ''datetime search''.
 * Second component provides some options. For example, demands exact or fuzzy match
 * Third and fourth components are type-dependent and containing search string and additional limits

The format is as follows:
  {{{ [type/module specification] [global flags] <search string> [limits] }}}
Everything besides search string is optional. By default if the type is not specified, the search for channel and group names is performed.
