Hi,
Elasticsearch Version: 7.10.1
Getting the following error when trying to index a document
`{"_index":"test1","_type":"_doc","_id":"1000370980","status":400,"error":{"type":"illegal_argument_exception","reason":"cannot index term vector offsets when term vectors are not indexed (field=\"meta.contribGroup.contrib.lnameFname.suggest2._index_prefix\")"}}`
Providing the mapping for the concerned field below
> ```
> "lnameFname": {
> "type": "text",
> "analyzer": "sae_english_1",
> "search_analyzer": "sae_english_1_search",
> "copy_to": [
> "allMeta",
> "autoCompleteAuthor"
> ],
> "fields": {
> "keyword": {
> "type": "keyword",
> "ignore_above": 256
> },
> "lowercase": {
> "type": "keyword",
> "normalizer": "lowercase_normalizer",
> "ignore_above": 256

> "suggest1": {"type": "search_as_you_type"},
> "suggest2": {
> "type": "search_as_you_type",
> "index_options": "offsets",

> "analyzer": "sae_english_1",

This used to work fine before we upgraded Elasticsearch from **7.8.1** to 7.10.1
Any advice will be appreciated.
Thanks

term vector supposed to configure only root field and shingle subfields, not the prefix but seems like Elasticsearch is trying to create a vector for \_index\_prefix field also for **search-as-you-type** field type.

The simple example to replicate the issue
**Template**
```
PUT _index_template/vector-test
{
"index_patterns": ["vector-test"],
"template": {
"mappings": {
"properties": {
"TestFieldName": {
"type": "text",
"fields": {
"suggest2": {
"type": "search_as_you_type",
"index_options": "offsets",
"term_vector": "with_positions_offsets"
}
}
}
}
}
}
}
```
**Index Data**
```
PUT /vector-test/_doc/1'
{
"TestFieldName" : "Test1 Field Value"
}
```
**Error Message**
```
"error" : {
"root_cause" : [
{
"type" : "illegal_argument_exception",
"reason" : "cannot index term vector offsets when term vectors are not indexed (field=\"TestFieldName.suggest2._index_prefix\")"
}
],
"type" : "illegal_argument_exception",
"reason" : "cannot index term vector offsets when term vectors are not indexed (field=\"TestFieldName.suggest2._index_prefix\")"
},
"status" : 400
}
```
As I mentioned the same test case working okay in v7.8.1. Not sure what I am missing.
Thank you for any help.

That looks like a legitimate bug, can you open an issue on github with the same reproduction ?
