複合詞拆分器

「decompounder 」篩選器會根據指定的字典，將複合詞拆分為個別組成部分，使搜尋複合詞的各部分更加容易。此篩選器對於經常使用複合詞的語言（例如德語）特別有用。

組成部分字典可透過 `word_list ` 參數直接提供，或透過 `word_list_file ` 參數從已註冊的檔案資源中載入。

設定

decompounder 篩選器可透過word_list 參數直接提供其組成詞彙表，或透過word_list_file 參數從已註冊的檔案資源載入。

內嵌詞彙表

decompounder 篩選器是 Milvus 中的自訂篩選器。若要使用它，請在篩選器配置中指定"type": "decompounder" ，並搭配word_list 參數，該參數提供待辨識的單字組成部分字典。

    "tokenizer": "standard",
    "filter":[{
        "type": "decompounder", # Specifies the filter type as decompounder

decompounder 過濾器接受以下可配置參數。

參數	說明
word_list	用於拆分複合詞的詞彙組件清單。此字典決定複合詞如何被分解為個別詞彙。

decompounder 過濾器是針對分詞器所產生的詞項進行處理，因此必須與分詞器搭配使用。有關 Milvus 中可用的分詞器清單，請參閱「標準分詞器」及其相關頁面。

定義完「analyzer_params 」後，您可在定義集合架構時將其套用至VARCHAR 欄位。這使 Milvus 能使用指定的分析器處理該欄位中的文字，以實現高效的詞元化與篩選。詳細資訊請參閱「使用範例」。

從檔案資源載入單字組成部分Compatible with Milvus 3.0.x

對於大型組件字典（尤其是完整語言的單字清單），請將組件儲存於檔案中，並將該檔案註冊為遠端檔案資源，然後透過 `word_list_file ` 參數在篩選器中引用該檔案。您可以單獨使用 `word_list_file `，或與內嵌的 `word_list` 搭配使用；當兩者皆設定時，篩選器會將這兩個來源合併為單一組件清單。

該檔案為純 UTF‑8 文字，每行包含一個元件詞。例如：

dampf
schiff
fahrt
brot
backen
automat

將檔案上傳至您的 Milvus 叢集所設定使用的物件儲存庫，然後進行註冊：

from pymilvus import MilvusClient

client = MilvusClient(uri="http://localhost:19530")

# Register the uploaded file under a name you'll reference from analyzer configs.
client.add_file_resource(
    name="de_components",
    path="file/decompounder.txt",    # full S3 object key, including the rootPath prefix
)

透過 `word_list_file` 在篩選器中引用已註冊的資源：

analyzer_params = {
    "tokenizer": "standard",
    "filter": [{
        "type": "decompounder",
        "word_list_file": {
            "type": "remote",
            "resource_name": "de_components",
            "file_name": "decompounder.txt",
        },
    }],
}

word_list_file 參數接受具有以下欄位的物件：

欄位	說明
type	資源類型。若要註冊透過add_file_resource 註冊的檔案，請使用"remote" 。至於自託管部署中使用的"local" 變體，請參閱《管理檔案資源》。
resource_name	該檔案在add_file_resource 註冊時所使用的名稱。
file_name	已註冊資源的物件儲存路徑中的檔案名稱部分（例如，若資源是透過path="file/decompounder.txt" 註冊的，則為"decompounder.txt" ）。
