type DocValuesFormat 

type DocValuesFormat struct {
	// contains filtered or unexported fields
}

DocValuesFormat * plain text doc values format. FOR RECREATIONAL USE ONLY the .dat file contains the data. for numbers this is a "fixed-width" file, for example a single byte range: 

field myField
  type NUMERIC
  minvalue 0
  pattern 000
005
T
234
T
123
T
...

so a document's value (delta encoded from minvalue) can be retrieved by seeking to startOffset + (1+pattern.length()+2)*docid. The extra 1 is the newline. The extra 2 is another newline and 'T' or 'F': true if the value is real, false if missing. for bytes this is also a "fixed-width" file, for example: 

field myField
  type BINARY
  maxlength 6
  pattern 0
length 6
foobar[space][space]
T
length 3
baz[space][space][space][space][space]
T
...

so a doc's value can be retrieved by seeking to startOffset + (9+pattern.length+maxlength+2)*doc the extra 9 is 2 newlines, plus "length " itself. the extra 2 is another newline and 'T' or 'F': true if the value is real, false if missing. for sorted bytes this is a fixed-width file, for example: 

field myField
  type SORTED
  numvalues 10
  maxLength 8
  pattern 0
  ordpattern 00
length 6
foobar[space][space]
length 3
baz[space][space][space][space][space]
...
03
06
01
10
...

so the "ord section" begins at startOffset + (9+pattern.length+maxlength)*numValues. a document's ord can be retrieved by seeking to "ord section" + (1+ordpattern.length())*docid an ord's value can be retrieved by seeking to startOffset + (9+pattern.length+maxlength)*ord for sorted set this is a fixed-width file very similar to the SORTED case, for example: 

  field myField
    type SORTED_SET
    numvalues 10
    maxLength 8
    pattern 0
    ordpattern XXXXX
  length 6
  foobar[space][space]
  length 3
  baz[space][space][space][space][space]
  ...
  0,3,5
  1,2

  10
  ...

so the "ord section" begins at startOffset + (9+pattern.length+maxlength)*numValues.
a document's ord list can be retrieved by seeking to "ord section" + (1+ordpattern.length())*docid
this is a comma-separated list, and it's padded with spaces to be fixed width. so trim() and split() it.
and beware the empty string! an ord's value can be retrieved by seeking to
startOffset + (9+pattern.length+maxlength)*ord for sorted numerics, it's encoded (not very creatively)
as a comma-separated list of strings the same as binary. beware the empty string! the reader can just
scan this file when it opens, skipping over the data blocks and saving the offset/etc for each field.
