## 前端使用

在浏览器上前往`localhost:5000/`

### **每次搜索的时候搜索框里一定得有东西！**

1. **无位置约束：**

   1. word word 搜索：直接输入即可

      ```

      中国 强大

      ```

   2. word/phrase word/phrase搜索：`词语/词性`

      ```

      中国/n 强大/a

      ```

2. **有位置约束：**

   1. word word 搜索 + 位置约束：直接输入即可，在`restriction`输入2-5之间的数值

      ```

      中国 强大 

      2

      ```

   2. word/phrase word/phrase搜索 + 位置约束：`词语/词性`，在`restriction`输入2-5之间的数值

      ```

      中国/n 强大/a

      2

      ```

3. **前四种的混合：**

   即搜索词中，有的词可以有phrase也可以没有，位置约束也是可加可以不加。比如
