I am an expert in the field, well-versed in various concepts and topics related to the information provided in the code snippet. My depth of knowledge allows me to offer insights and explanations on a wide range of subjects. Now, let's delve into the concepts used in the article.

The provided code appears to be a part of a web application, possibly related to searching and displaying information. Here are some key concepts and functionalities used in the code:

Search Functionality:
- The code seems to handle a search feature with a focus on textbooks, courses, and topics.
- It utilizes a while-typing search mechanism, where results are dynamically updated as the user types.
Textbook Information:
- The code fetches information about textbooks, including titles, editions, and authors.
- It categorizes textbooks into recently opened and recommended, possibly for user convenience.
Curriculum and Topics:
- The application seems to organize information into curriculum and topics, possibly related to educational content.
Solution Display:
- There is a section dedicated to displaying solutions, which might include answers to questions or information related to specific courses or textbooks.
User Interaction:
- The code includes user interaction elements, such as handling mouse events, resizing the popup, and updating content based on user input.
Ajax Requests:
- The code makes Ajax requests to the server to fetch data dynamically without refreshing the entire page.
MathJax Integration:
- There is integration with MathJax, suggesting that the application may involve mathematical content, such as equations or formulas.
Local Storage:
- The application uses local storage to store and retrieve information about previously opened and recommended textbooks.
Responsive Design:
- The code includes functionality to handle window resizing, ensuring a responsive design for the popup.
Conditional Rendering:
- Certain sections and elements are rendered conditionally based on the presence of data or user actions.

These are the overarching concepts inferred from the provided code. If you have specific questions or if there's a particular aspect you'd like more details on, feel free to ask.
