如何从draftjs中检索文本

import React, { useState } from 'react';
import { Editor, EditorState, convertToRaw } from 'draft-js';

const TextSearchExample = () => {
  const [editorState, setEditorState] = useState(EditorState.createEmpty());

  const handleEditorChange = (newEditorState) => {
    setEditorState(newEditorState);

    const contentState = newEditorState.getCurrentContent();
    const rawContentState = convertToRaw(contentState);
    const text = rawContentState.blocks.map(block => block.text).join('\n');
    
    // 在这里可以对text进行检索操作
    console.log(text);
  }

  return (
    <Editor
      editorState={editorState}
      onChange={handleEditorChange}
    />
  );
}

export default TextSearchExample;
