    120120Ordering of the result set can be requested by setting <orderBy> to one of the valid values listed in the orderByFieldList accesible via the getList operation. Currently these are: 
    121121  textRelevance:: 
    122     Ranking metric based on relevance of match to search term (further info?) 
     122    Ranking metric based on relevance of match to search term (metric derived by postgres text ranking function). 
    123123  date::  
    124     Specifically, the start date of the date range given for the temporal coverage of the metadata record  
    125   dataCentre::  
    126     The repository identifier of the curator of the described entity (or most appropriate equivalent field) 
     124    The start date of the date range given for the temporal coverage of the metadata record. Records with no start date defined are treated as if their start date is later than that last record with a start date defined. [Note : this is a known bug currently causing records with no start date to be treated as if their start date is AFTER that of the last record with a start date. With orderByDirection set to "ascending" this is less of a problem, but at present, with orderByDirection set to "descending", these "incomplete" records are the first in the results list. See ticket ???]  
     125  dataCentre:: 
     126    The name of the data centre supplying the metadata record. In the case of records supplied in DIF format, this is the Data_Centre/Short_Name field. In the case of other metadata formats, the most appropriate equivalent field is used as this index (e.g. "" for MDIP format) 
    127127  datasetResultsetPopularity:: 
    128128    ?? 
     
    136136    ?? 
    137137 
    138 In addition, the direction of ordering (ascending or descending) can be specified. If omitted, the default direction is descending.
