search

Search for the text string in a source for data identified with that string.

If text is NULL then no text filter will be applied, and thus, no media items from this will be filtered. If this does not support NULL-text search operations it should notiy the client by setting GRL_CORE_ERROR_SEARCH_NULL_UNSUPPORTED in callback's error parameter.

This method is asynchronous.

Parameters:

this	a source
callback	the user defined callback
keys	the List of KeyID<!-- -- >s to request
options	options wanted for that operation
text	the text to search
user_data	the user data to pass in the callback

Returns:

the operation identifier
