 # eqa-search
 
+# Enhanced QA Search
+
+## Description
+
+**Enhanced question-answering** is the process of creating the knowledge base and generating answers with LLMs(large language model), thus preventing illusions. It involves inserting data as knowledge base and querying questions, and **eqa-search** is used to query questions from knowledge base.
+
+
+<br />
+
+
+## Code Example
+
+### **Create pipeline and set the configuration**
+
+> More parameters refer to the Configuration.
+
+```python
+from towhee import AutoPipes, AutoConfig
+
+config = AutoConfig.load_config('eqa-search')
+config.collection_name = 'chatbot'
+
+p = AutoPipes.pipeline('eqa-search', config=config)
+res = p('https://raw.githubusercontent.com/towhee-io/towhee/main/README.md')
+```
+
+
+<br />
