41  Returns results for URLs like C<search/suggest/FieldName>  Returns results for REST URIs like:
42    
43    C<search/suggest?search=FieldName&show=TitleProper&FieldName=query%20string>
44    
45    It will use C<search> field to filter results (and using additional
46    C<FieldName> as value of search) and return C<TitleProper> field
47    for results.
48    
49    If C<search> field has magic value <all>, it will search over all data, not
50    just one specified field:
