 Loop through all user-selected sources and submit queries to each source.
    • Changed:
    <
    <    		 For each source, verify that all user-selected parameters are supported. If they are not, the query to that source will fire an error event indicating that the source does not support the specified query .
    >
    >    		 For each source, verify that all user-selected parameters are supported. If they are not, the query to that source will fire an error event indicating that the source does not support the specified query. The one exception to this case occurs when the user has selected no "experimental info" (aka data type) parameter. If no data type parameter is selected, query all data types available for that source.

    Changed:
    <
    <    		 Possibilities to implement in the future:

    • Compile the list of supported parameters for each source prior to the search. This list can then be used to constrain the Search GUI options so that the user cannot select invalid source/parameter combinations.
    >
    >    		 To implement in the future:

    • When an adequate keyword search capability is available, add an alternative Search GUI to support keyword queries.
