The Solr example schema says “<!-- Valid attributes for fields:”, but omits omitPositions, omitTermFreqAndPositions, sortMissingFirst, and sortMissingLast.
It would also be helpful to have a clarifying note that distinguishes omitPositions and omitTermFreqAndPositions from termPositions and termVectors. I’m not positive, but is it simply that the omitXxx attributes control what gets indexed versus the termXxx attributes controlling what is what can be retrieved, and that settings of the latter do not influence the former? -- Jack Krupansky
