```lua
nil  -- or
{
  key = "value"
}
```

**Example call**

```lua
local result = bds.embeddings.compute_similarities("id-1", {"id-2", "id-3"})
```

### embeddings.dismiss_pair

- post_id_b (string, required)

**Response specification**

- Return type: `boolean`

**Example response**

```lua
true
```

**Example call**

```lua
local result = bds.embeddings.dismiss_pair("value", "value")
```

### embeddings.find_duplicates

Find duplicate post candidates for the current project.

**Parameters**

- None

**Response specification**

- Return type: `table | nil`
- Nullability: Returns `nil` when no matching value exists or the operation cannot produce a value.

**Example response**

```lua
nil  -- or
{
  key = "value"
}
```

**Example call**

```lua
local result = bds.embeddings.find_duplicates()
```

### embeddings.find_similar

Find posts similar to the given post id.

**Parameters**

- post_id (string, required)
- limit (integer, optional)

**Response specification**

- Return type: `table | nil`
- Nullability: Returns `nil` when no matching value exists or the operation cannot produce a value.

**Example response**

```lua
nil  -- or
{
  key = "value"
}
```

**Example call**

```lua
local result = bds.embeddings.find_similar("id-1", 10)
```

### embeddings.get_progress

Get embedding index progress for the current project.

**Parameters**

- None

**Response specification**

- Return type: `table | nil`
- Nullability: Returns `nil` when no matching value exists or the operation cannot produce a value.

**Example response**

```lua
nil  -- or
{
  key = "value"
}
```

**Example call**

```lua
local result = bds.embeddings.get_progress()
```

### embeddings.index_unindexed_posts

Index posts missing embeddings for the current project.

**Parameters**

- None

**Response specification**

- Return type: `table | nil`
- Nullability: Returns `nil` when no matching value exists or the operation cannot produce a value.

**Example response**

```lua
nil  -- or
{
  key = "value"
}
```

**Parameters**

- post_id (string, required)
- exclude_tags (table, optional)

**Response specification**

- Return type: `table | nil`
- Nullability: Returns `nil` when no matching value exists or the operation cannot produce a value.
