    convertToLuceneQuery in interface LuceneQueryMapper<FieldExistsQuery>
    
    Parameters:
    
    query - the query to convert
    
    Returns:
    
    the lucene query corresponding to the search query. null can be returned and signifies that no mapped query is necessary for the mapped query.
