Is it possible to get detailed information about the returned results and how and why they were scored? Solr has a debug option where you can see exactly how a given document was scored, and can also return an explain plan for a query.
I have been searching the Azure Search docs, but i don't see anything like this mentioned there.
Is there any sort of debugging capability in Azure Search, and if not, is any such feature(s) on the roadmap for this service?
Update: Adding more for clarification, in the hopes of getting a response:
For example, here is an example of the debug information for a document returned by a query:
"2122aaea-dac2-4934-b6d2-5f38bdc906de": {
"match": true,
"value": 1.1052036,
"description": "weight(_text_:house in 7) [SchemaSimilarity], result of:",
"details": [
{
"match": true,
"value": 1.1052036,
"description": "score(freq=2.0), product of:",
"details": [
{
"match": true,
"value": 1.8216125,
"description": "idf, computed as log(1 + (N - n + 0.5) / (n + 0.5)) from:",
"details": [
{
"match": true,
"value": 5,
"description": "n, number of documents containing term"
},
{
"match": true,
"value": 33,
"description": "N, total number of documents with field"
}
]
},
{
"match": true,
"value": 0.6067172,
"description": "tf, computed as freq / (freq + k1 * (1 - b + b * dl / avgdl)) from:",
"details": [
{
"match": true,
"value": 2.0,
"description": "freq, occurrences of term within document"
},
{
"match": true,
"value": 1.2,
"description": "k1, term saturation parameter"
},
{
"match": true,
"value": 0.75,
"description": "b, length normalization parameter"
},
{
"match": true,
"value": 248.0,
"description": "dl, length of field (approximate)"
},
{
"match": true,
"value": 224.0,
"description": "avgdl, average length of field"
}
]
}
]
}
]
}
The answer at this moment is no. Unfortunately there's no "debug" / "explain" functionality available but as this is a frequent request, I would not be surprised if they add it in the future.
