# Cross Language Search
## Search cliassical CN with modern ZH
* In some cases, Classical Chinese feels like another language, I even trained 2 translation model to prove this point.
* That's why, when people wants to be savvy about their words, we choose to quote our ancestors. It's exactly like westerners like to quote Latin or Shakespare, the difference is we have a much bigger pool to choose.
* This model helps you **find** text within **ancient Chinese** literature, but you can **search with modern Chinese**

# 跨语种搜索
## 博古搜今
```python
from unpackai.interp import CosineSearch
from sentence_transformers import SentenceTransformer
import pandas as pd
import numpy as np

TAG = "raynardj/xlsearch-cross-lang-search-zh-vs-classicical-cn"
encoder = SentenceTransformer(TAG)

# all_lines is a list of all your sentences
# all_lines 是一个你所有句子的列表， 可以是一本书， 按照句子分割， 也可以是很多很多书
all_lines = ["句子1","句子2",...]
vec = encoder.encode(all_lines, batch_size=32, show_progress_bar=True)

# consine距离搜索器
cosine = CosineSearch(vec)

def search(text):
    enc = encoder.encode(text) # encode the search key
    order = cosine(enc) # distance array
    sentence_df = pd.DataFrame({"sentence":np.array(all_lines)[order[:5]]})
    return sentence_df
```

将史记打成句子以后， 搜索效果如下
```python
>>> search("他是一个很慷慨的人")
```
```
