Is there any way to record both the title and the sentence after the title in plain text And facilitate a quick search for the specified title to get the sentence after the searched title

Yes, you can create a plain text file where each entry contains the title followed by the sentence. For example:

Title 1: This is the sentence after title 1. Title 2: Here's the sentence after title 2. Title 3: The sentence after title 3 is this.

To search for a specific title and get the sentence after it, you can use the "find" function in your text editor or word processor. Alternatively, you can import the plain text file into a database program and set up a search function to quickly find the desired title and sentence
