*** ** * ** ***


```
@ExperimentalAppSearchApi
public final class SearchResult.EmbeddingMatchInfo
```

<br />

*** ** * ** ***

This class represents match objects for any snippets that might be present in `https://developer.android.com/reference/androidx/appsearch/app/SearchResults` from an embedding query. Using this class, you can get:

- the semantic score of the matching vector with the embedding query
- the query embedding vector index - the index of the query `https://developer.android.com/reference/androidx/appsearch/app/EmbeddingVector` in the list returned by `https://developer.android.com/reference/androidx/appsearch/app/SearchSpec#getEmbeddingParameters()`
- the embedding search metric type for the corresponding query

for each vector match in the document.

## Public constructors

### EmbeddingMatchInfo

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/appsearch#1.1.0)

```
@ExperimentalAppSearchApi
public EmbeddingMatchInfo(
    double semanticScore,
    int queryEmbeddingVectorIndex,

Creates a new immutable EmbeddingMatchInfo.

| Parameters |
|---|---|
| `double semanticScore` | the semantic score of the embedding match against the query vector. |
| `int queryEmbeddingVectorIndex` | the index of the matched query embedding vector in `https://developer.android.com/reference/androidx/appsearch/app/SearchSpec#getEmbeddingParameters()` |
| `int embeddingSearchMetricType` | the search metric type used to calculate the score for the match and the query vector |
