+ create a LAYER node for each layer you wish to use; layers may be used in 
  multiple map files, but do not duplicate layers here; do not create a LAYER 
  node for query layers (*_Identify, *_IdentifySelect *_Search, 
  *_SearchSelect); set UID if you wish to make the layer queryable (identify); 
  SEARCHFIELDS are used to define layers you wish to search on, UID must be 
  set and this value is used as the unique identifier for searching; 
  BOTTOMFIELDS are those fields from the DBF file you wish to display as 
  query results in the footer; SIDEFIELDS are query results that display in 
  the left frame of the application; LINKFIELDS are used for links embedded 
  in the query results table; the NAME node must match the field names defined 
  in BOTTOMFIELDS and SIDEFIELDS; PREFIX is the link itself; ANNOTATIONFIELDS 
  are used for annotation layers; the NAME and DISPLAY nodes are set to those

  YourLayerName_SearchSelect
+ for layers you wish to query (identify or select), modify the TEMPLATE 
  "YourQueryFile.html" to reference the corresponding query file
+ for layers you wish to identify, set MAXFEATURES to the value of 
  MAXQUERYFEATURES of mapserv.xml plus one
