Länge

Der Filter „ length “ entfernt Token, die die festgelegten Längenanforderungen nicht erfüllen, sodass Sie die Länge der bei der Textverarbeitung beibehaltenen Token steuern können.

Konfiguration

Der Filter „ length “ ist ein benutzerdefinierter Filter in Milvus, der durch die Einstellung „ "type": "length" “ in der Filterkonfiguration festgelegt wird. Sie können ihn als Wörterbuch innerhalb des „ analyzer_params “ konfigurieren, um Längenbeschränkungen zu definieren.

analyzer_params = {
    "tokenizer": "standard",
    "filter":[{
        "type": "length", # Specifies the filter type as length
        "max": 10, # Sets the maximum token length to 10 characters
    }],
}

import java.util.Collections;
import java.util.HashMap;
import java.util.Map;

Map<String, Object> analyzerParams = new HashMap<>();
analyzerParams.put("tokenizer", "standard");
analyzerParams.put("filter",
        Collections.singletonList(new HashMap<String, Object>() {{
            put("type", "length");
            put("max", 10);
        }}));

analyzerParams := map[string]any{"tokenizer": "standard",
    "filter": []any{map[string]any{
        "type": "length",
        "max":  10,
    }}}

let analyzer_params = serde_json::json!({
    "tokenizer": "standard",
    "filter": [
        {
            "type": "length",
            "max": 10
        }
    ]
});

nlohmann::json analyzer_params = {
    {"tokenizer", "standard"},
    {"filter", {
        {{"type", "length"}, {"max", 10}}
    }}
};

const analyzer_params = {
    "tokenizer": "standard",
    "filter":[{
        "type": "length", // Specifies the filter type as length
        "max": 10, // Sets the maximum token length to 10 characters
    }],
};

using System.Collections.Generic;

var analyzerParams = new Dictionary<string, object>
{
    ["tokenizer"] = "standard",
    ["filter"] = new object[]
    {
        new Dictionary<string, object>
        {
            ["type"] = "length", // Specifies the filter type as length
            ["max"] = 10 // Sets the maximum token length to 10 characters
        }
    }
};

# restful
analyzerParams='{
  "tokenizer": "standard",
  "filter": [
    {
      "type": "length",
      "max": 10
    }
  ]
}'

Der Filter „ length “ akzeptiert die folgenden konfigurierbaren Parameter.

Parameter	Beschreibung
max	Legt die maximale Tokenlänge fest. Token, die länger als diese Länge sind, werden entfernt.

Der Filter „ length “ verarbeitet die vom Tokenizer generierten Terme und muss daher in Kombination mit einem Tokenizer verwendet werden. Eine Liste der in Milvus verfügbaren Tokenizer finden Sie unter „Standard-Tokenizer“ und den zugehörigen Seiten.

Nachdem Sie „ analyzer_params “ definiert haben, können Sie diese bei der Definition eines Sammlungsschemas auf ein „ VARCHAR “-Feld anwenden. Dadurch kann Milvus den Text in diesem Feld mit dem angegebenen Analysator verarbeiten, um eine effiziente Tokenisierung und Filterung zu gewährleisten. Weitere Informationen finden Sie unter „Anwendungsbeispiel“.

Beispiele

Bevor Sie die Analyzer-Konfiguration auf Ihr Sammlungsschema anwenden, überprüfen Sie deren Verhalten mithilfe der Methode „ run_analyzer “.
