Cnalphanumonly

Il filtro cnalphanumonly rimuove i token che contengono caratteri diversi dai caratteri cinesi, dalle lettere inglesi o dalle cifre.

Configurazione

Il filtro cnalphanumonly è integrato in Milvus. Per utilizzarlo, è sufficiente specificarne il nome nella sezione filter all'interno di analyzer_params.

analyzer_params = {
    "tokenizer": "jieba",
    "filter": ["cnalphanumonly"],
}

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

Map<String, Object> analyzerParams = new HashMap<>();
analyzerParams.put("tokenizer", "jieba");
analyzerParams.put("filter", Collections.singletonList("cnalphanumonly"));

analyzerParams := map[string]any{"tokenizer": "jieba", "filter": []any{"cnalphanumonly"}}

let analyzer_params = serde_json::json!({"tokenizer": "jieba", "filter": ["cnalphanumonly"]});

nlohmann::json analyzer_params = {
    {"tokenizer", "jieba"},
    {"filter", {"cnalphanumonly"}}
};

const analyzer_params = {
    "tokenizer": "jieba",
    "filter": ["cnalphanumonly"],
};

using System.Collections.Generic;

var analyzerParams = new Dictionary<string, object>
{
    ["tokenizer"] = "jieba",
    ["filter"] = new[] { "cnalphanumonly" }
};

# restful
analyzerParams='{
  "tokenizer": "jieba",
  "filter": [
    "cnalphanumonly"
  ]
}'

Il filtro " cnalphanumonly " opera sui termini generati dal tokenizer, pertanto deve essere utilizzato in combinazione con un tokenizer. Per un elenco dei tokenizer disponibili in Milvus, consultare Jieba e le pagine correlate.

Dopo aver definito gli analyzer_params, è possibile applicarli a un campo VARCHAR durante la definizione dello schema di una collezione. Ciò consente a Milvus di elaborare il testo in quel campo utilizzando l’analizzatore specificato per una tokenizzazione e un filtraggio efficienti. Per ulteriori dettagli, consultare Esempio di utilizzo.

Esempi

Prima di applicare la configurazione dell’analizzatore allo schema della collezione, verificarne il comportamento utilizzando il metodo ` run_analyzer `.

Configurazione dell’analizzatore

analyzer_params = {
    "tokenizer": "jieba",
    "filter": ["cnalphanumonly"],
}

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

Map<String, Object> analyzerParams = new HashMap<>();
analyzerParams.put("tokenizer", "jieba");
analyzerParams.put("filter", Collections.singletonList("cnalphanumonly"));

analyzerParams := map[string]any{"tokenizer": "jieba", "filter": []any{"cnalphanumonly"}}

let analyzer_params = serde_json::json!({"tokenizer": "jieba", "filter": ["cnalphanumonly"]});

nlohmann::json analyzer_params = {
    {"tokenizer", "jieba"},
    {"filter", {"cnalphanumonly"}}
};

const analyzer_params = {
    "tokenizer": "jieba",
    "filter": ["cnalphanumonly"],
};

using System.Collections.Generic;

var analyzerParams = new Dictionary<string, object>
{
    ["tokenizer"] = "jieba",
    ["filter"] = new[] { "cnalphanumonly" }
};

# restful
analyzerParams='{
  "tokenizer": "jieba",
  "filter": [
    "cnalphanumonly"
  ]
}'
