在我之前的文章 "Elasticsearch：使用 LangChain 文档拆分器进行文档分块" 中，我详述了如何通过 LangChain 对大的文档进行分块。那个分块的动作是通过 LangChain 在 Python 中进行实现的。对于使用版权的开发者来说，我们实际上是可以通过 ingest pipeline 来完成这个操作的。
这个交互式笔记本将：
- 将模型 sentence-transformers__all-minilm-l6-v2 从 Hugging Face 加载到 Elasticsearch ML Node 中
- 创建一个索引和摄取管道，将大字段分成更小的通道，并使用模型对它们进行向量化
- 执行搜索并返回包含最相关段落的文档
安装
安装 Elasticsearch 及 Kibana
如果你还没有安装好自己的 Elasticsearch 及 Kibana，那么请参考一下的文章来进行安装：
在安装的时候，请选择 Elastic Stack 8.x 进行安装。在安装的时候，我们可以看到如下的安装信息：
环境变量
在启动 Jupyter 之前，我们设置如下的环境变量：
export ES_USER="elastic"
export ES_PASSWORD="xnLj56lTrH98Lf_6n76y"
export ES_ENDPOINT="localhost"
请在上面修改相应的变量的值。这个需要在启动 jupyter 之前运行。
拷贝 Elasticsearch 证书
我们把 Elasticsearch 的证书拷贝到当前的目录下：
$ pwd
/Users/liuxg/python/elser
$ cp ~/elastic/elasticsearch-8.12.0/config/certs/http_ca.crt .
$ ls http_ca.crt
http_ca.crt
安装 Python 依赖包
python3 -m pip install -qU elasticsearch eland load_dotenv
准备数据
我们在项目的根目录下创建如下的文件：
workplace-docs.json

This policy applies to all employees and aims to foster a culture of continuous improvement, professional growth, and open communication between employees and management.\nPerformance Planning and Goal Setting\nAt the beginning of each performance cycle, employees and their supervisors will collaborate to set clear, achievable, and measurable performance goals. These goals should align with the company\u2019s strategic objectives and take into account the employee\u2019s job responsibilities, professional development, and career aspirations.\nOngoing Feedback and Communication\nThroughout the performance cycle, employees and supervisors are encouraged to engage in regular, constructive feedback and open communication. This includes discussing progress towards goals, addressing challenges, and identifying opportunities for improvement or additional support. Regular check-ins and updates help ensure that employees stay on track and receive the guidance they need to succeed.\nPerformance Evaluation\nAt the end of each performance cycle, employees will participate in a formal performance evaluation with their supervisor. This evaluation will assess the employee\u2019s overall performance, including their achievements, areas for improvement, and progress towards goals. Both the employee and supervisor should come prepared to discuss specific examples, accomplishments, and challenges from the performance period.\nPerformance Ratings\nBased on the performance evaluation, employees will receive a performance rating that reflects their overall performance during the cycle. The rating system should be clearly defined and consistently applied across the organization. Performance ratings will be used to inform decisions regarding promotions, salary increases, and other rewards or recognition.\nPromotions and Advancements\nHigh-performing employees who consistently demonstrate strong performance, leadership, and a commitment to the company\u2019s values may be considered for promotions or other advancement opportunities. Promotions will be based on factors such as performance ratings, skills, experience, and the needs of the organization. Employees interested in pursuing a promotion should discuss their career goals and development plans with their supervisor.\nPerformance Improvement Plans\nEmployees who receive a low performance rating or are struggling to meet their performance goals may be placed on a Performance Improvement Plan (PIP). A PIP is a structured plan designed to help the employee address specific areas of concern, set achievable improvement goals, and receive additional support or resources as needed. Employees on a PIP will be closely monitored and re-evaluated at the end of the improvement period to determine if satisfactory progress has been made.\nRecognition and Rewards\nOur company believes in recognizing and rewarding employees for their hard work and dedication. In addition to promotions and salary increases, employees may be eligible for other forms of recognition or rewards based on their performance. This may include bonuses, awards, or other incentives designed to motivate and celebrate employee achievements. The specific criteria and eligibility for these rewards will be communicated by the HR department or management.\n",

创建应用并展示
我们在当前的目录下打入如下的命令来创建 notebook：
$ pwd
/Users/liuxg/python/elser
$ jupyter notebook
连接到 Elasticsearch
from elasticsearch import Elasticsearch
from dotenv import load_dotenv
import os
from elasticsearch import Elasticsearch
load_dotenv()
elastic_user=os.getenv('ES_USER')
elastic_password=os.getenv('ES_PASSWORD')
elastic_endpoint=os.getenv("ES_ENDPOINT")
url = f"https://{elastic_user}:{elastic_password}@{elastic_endpoint}:9200"
client = Elasticsearch(url, ca_certs = "./http_ca.crt", verify_certs = True)
print(client.info())
从上面的输出中，我们可以看到连接是成功的。
从 huggingface 加载模型
你需要的第一件事是一个模型，用于从块中创建文本嵌入，你可以使用任何你想要的东西，但此示例将在 minilm-l6-v2 模型上端到端运行。我们可以使用 eland 库上传文本嵌入模型。
MODEL_ID = "sentence-transformers__all-minilm-l6-v2"
!eland_import_hub_model --url https://elastic:xnLj56lTrH98Lf_6n76y@localhost:9200 \
--hub-model-id sentence-transformers/all-MiniLM-L6-v2 \
--task-type text_embedding \
--ca-cert ./http_ca.crt \
--clear-previous \
--start
你需要根据自己的 Elasticsearch 配置修改上面的用户名及密码。整个下载过程需要一定的时间。我们可以打开 Kibana 来查看模型的下载：
从上面的输出中，我们可以看到部署是成功的。
管道中的分块和推断
下一步是定义一个摄取管道，将文本字段分解为存储在段落字段中的文本块。 该管道有两个处理器，第一个脚本处理器将文本字段分解为通过正则表达式存储在段落字段中的句子数组。 要进一步研究，请阅读正则表达式的高级功能，例如负向后查找和正向后查找，以了解它如何尝试在句子边界上正确分割，而不是在 Mr. 或 Mrs. 或 Ms. 上分割，并保留句子中的标点符号。 只要总字符串长度低于传递给脚本的参数，它还会尝试将句子块连接在一起。 接下来每个处理器通过推理处理器在每个句子上运行文本嵌入模型：
# Setup the pipeline
CHUNK_SIZE = 400
client.ingest.put_pipeline(
id="chunk_text_to_passages",
processors=[
{
"script": {
"description": "Chunk body_content into sentences by looking for . followed by a space",
"lang": "painless",
"source": """
String[] envSplit = /((?<!M(r|s|rs)\.)(?<=\.) |(?<=\!) |(?<=\?) )/.split(ctx['text']);
ctx['passages'] = new ArrayList();
int i = 0;
boolean remaining = true;
if (envSplit.length == 0) {
return
} else if (envSplit.length == 1) {
Map passage = ['text': envSplit[0]];ctx['passages'].add(passage)
} else {
while (remaining) {
Map passage = ['text': envSplit[i++]];
while (i < envSplit.length && passage.text.length() + envSplit[i].length() < params.model_limit) {passage.text = passage.text + ' ' + envSplit[i++]}
if (i == envSplit.length) {remaining = false}
ctx['passages'].add(passage)
}
}
""",
"params": {
"model_limit": CHUNK_SIZE
}
}
},
{
"foreach": {
"field": "passages",
"processor": {
"inference": {
"field_map": {
"_ingest._value.text": "text_field"
},
"model_id": MODEL_ID,

{

"timestamp": "{{{ _ingest.timestamp }}}"
}
]
}
}
]
}
}
}
}
]
)
更多参考，请详细阅读文章 "Elasticsearch：通过摄取管道加上嵌套向量对大型文档进行分块轻松地实现段落搜索"。
设置索引
下一步是准备映射以处理将在摄取管道期间创建的句子数组和向量对象。 对于这个特定的文本嵌入模型，维度为 384，dot_product 相似度将用于最近邻计算：
INDEX_NAME = "chunk_passages_example"
# Setup the index
client.indices.create(
index=INDEX_NAME,
settings={
"index": {
"default_pipeline": "chunk_text_to_passages"
}
},
mappings={
"dynamic": "true",
"properties": {
"passages": {
"type": "nested",
"properties": {
"vector": {
"properties": {
"predicted_value": {
"type": "dense_vector",
"index": True,
"dims": 384,
"similarity": "dot_product"
}
}
}
}
}
}
}
)
添加文档
现在我们可以在 body_content 中添加包含大量文本的文档，并自动将它们分块，并且每个块文本由模型嵌入到向量中：
import json
from elasticsearch import helpers
with open('workplace-docs.json') as f:
docs = json.load(f)
operations = [
{
"_index": INDEX_NAME,
"_id": i,
"text": doc["content"],
"name": doc["name"]
} for i, doc in enumerate(docs)
]
# Add the documents to the index directly
response = helpers.bulk(
client,
operations,
refresh=True,
)
运行完上面的命令后，我们可以在 Kibana 中进行查看：
实用工具：漂亮地打印 Elasticsearch 响应
你的 API 调用将返回难以阅读的嵌套 JSON。 我们将创建一个名为 Pretty_response 的小函数，以从示例中返回漂亮的、人类可读的输出。
def pretty_response(response):
if len(response['hits']['hits']) == 0:
print('Your search returned no results.')
else:
for hit in response['hits']['hits']:
id = hit['_id']
score = hit['_score']
doc_title = hit['_source']['name']
passage_text = ""
for passage in hit['inner_hits']['passages']['hits']['hits']:
passage_text += passage["fields"]["passages"][0]['text'][0] + "\n\n"
pretty_output = (f"\nID: {id}\nDoc Title: {doc_title}\nPassage Text:\n{passage_text}\nScore: {score}\n")
print(pretty_output)
print("---")
进行查询
要搜索数据并返回与查询最匹配的块，你可以使用 inner_hits 和 knn 子句，以在查询的命中输出中返回文档的最佳匹配块。
下面你将看到返回最佳文档和最相关段落的响应。
response = client.search(
index=INDEX_NAME,
knn={
"inner_hits": {
"size": 1,
"_source": False,
"fields": [
"passages.text"
]
},
"field": "passages.vector.predicted_value",
"k": 3,
"num_candidates": 100,
"query_vector_builder": {
