Just trying to grasp the concept.
I want to search a text file where each line is a separate item to be searched. When text it entered by the user, I want to return all the lines in which that text appears. For example, if the text file has: I like apples. I went to the store. I bought an apple. If the user searches "apple", I want it to return the first and third sentences. Is each sentence a Token? Is the user input going to be a QueryParser? How should I read in the file so that each line of text is a token to search? Thanks in advance.
