Two scenarios, since the response shape differs — full detail on a single
replica, just the yes/no flag on a distributed query.
**Direct query to one replica** (`distrib=false`, or a standalone core) —
full detail, per suggester:
```
GET
/solr/mycollection_shard1_replica_n1/suggest?suggest=true&suggest.dictionary=slowSuggester&suggest.q=elec&suggest.count=5&distrib=false&wt=json
```
```json
{
"responseHeader": { "status": 0, "QTime": 3 },
"suggest": {
"slowSuggester": {
"elec": {
"numFound": 2,
"suggestions": [
{ "term": "electronics", "weight": 100, "payload": "" },
{ "term": "electric fan", "weight": 80, "payload": "" }
]
}
}
},
"suggesterIndexVersions": {
"slowSuggester": {
"builtFromIndexVersion": 41,
"currentIndexVersion": 43,
"stale": true
}
}
}
```
**Normal distributed SolrCloud query** (fans out to all shards, gets merged)
— just the aggregate flag, no per-shard numbers:
```
GET
/solr/mycollection/suggest?suggest=true&suggest.dictionary=slowSuggester&suggest.q=elec&suggest.count=5&wt=json
```
```json
{
"responseHeader": { "status": 0, "QTime": 12 },
"suggest": {
"slowSuggester": {
"elec": {
"numFound": 2,
"suggestions": [
{ "term": "electronics", "weight": 100, "payload": "" },
{ "term": "electric fan", "weight": 80, "payload": "" }
]
}
}
},
"suggesterStale": true
}
```
`suggesterStale: true` just means *at least one* of the shards that answered
this query was serving from a suggester that hadn't caught up yet — it doesn't
say which shard or by how much. To pin that down you'd fall back to the first
example (hit a specific replica directly with `distrib=false`) or check
`/admin/metrics`.
