Erick Erickson commented on SOLR-11770:
---------------------------------------

On another note:

If I switch my <uniqueKey> field from stored="true", docValues="false" to 
stored="false", docValues="true" the output changes. It seems like having the 
ID field present in docValues should allow it to be returned.

With stored=false, docValues=true:
  "termVectors":[]}


With stored=true, docValues=false:
"termVectors":[
    "GB18030TEST",[
      "uniqueKey","GB18030TEST"],
    "SP2514N",[
      "uniqueKey","SP2514N"],
    "6H500F0",[
      "uniqueKey","6H500F0"],
    "F8V7067-APL-KIT",[
      "uniqueKey","F8V7067-APL-KIT"],
    "IW-02",[
      "uniqueKey","IW-02"],
    "MA147LL/A",[
      "uniqueKey","MA147LL/A",
      "includes",[
        "cable",[],
        "earbud",[],
        "headphones",[],
        "usb",[]]],
    "adata",[
      "uniqueKey","adata"],
    "apple",[
      "uniqueKey","apple"],
    "asus",[
      "uniqueKey","asus"],
    "ati",[
      "uniqueKey","ati"]]}

> It looks like if {{tvrh}} request doesn't contain {{fl}} parameter and 
> document doesn't have any fields with term vectors then Solr returns NPE.
> Request: 
> {{tvrh?shards.qt=/tvrh&fq=field%3Avalue&wt=json&q=id%3A123&tv.tf=true}}.
> On our 'old' schema we had some fields with {{termVectors}} and even more 
> fields with position data. In our new schema we tried to remove unused data 
> so we dropped a lot of position data and some term vectors.
> Our documents are 'sparsely' populated - not all documents contain all fields.
> Above request was returning fine for our 'old' schema and returns 500 for our 
> 'new' schema - on exactly same Solr (6.6.2).
