''' Method to return the list of objects via GET method to the Resource (not concrete).
If the variable 'search_type' is present returns the appropriate bundles
which match the searching query. 'search_type' can have several values:
'name' - accompanied by 'q_str' variable containing the search string
returns all Bundles containing the q_str in their name.
'id' - accompanied by 'q_str' variable containing the search string
returns all Bundles containing a record that contains the q_str in their name.
'type' - accompanied by 'q_str' variable containing the search string
returns all Bundles containing a literal attribute with type prov:type
and value containing q_str.
'time' - accompanied by 'start' and/or 'end' variable containing the times
returns all Bundles with within the time frame [strat:end]
'any' - accompanied by 'q_str' variable containing the search string
returns all Bundles containing anything matching q_str.
