Search tool for compiling and organizing data

Overview:
I need a search tool that can go through all of my e-textbooks and pull out information based on specific keywords. The program should then compile the search results from multiple books into a single text file so that the entries can be sorted and evaluated. Since the input files are textbooks and reference material I will want the program to be able to copy images and tables in case the information isn't simply in a block of text. It will be important to be able to see where each entry in the text file came from in the original book so that I can check back if the entry is incomplete. Ideally the program would also be able to handle a queue of search terms so that I don't have to begin a new search manually every time one finishes. I'm open to any other optimizations or features you think might be necessary or useful.

EDIT: this should be compatible with Windows 10


Specific function:
1. Search a file for a keyword
2. Copy keyword and surrounding text to a separate text file (including reference file name and page number)
2a. amount of surrounding text to pull should be defined by user between a paragraph to a full page
2b. data selection should also pull tables and image files from the page when copying
3. Search the next file in the folder for the same keyword and copy that data to the same text file, repeating until the end of the folder is reached
4. Each search term has its own text file where the search data is copied (all the results for "spam" from all files goes to "spam.txt" while all the search results for "eggs" get dumped into "eggs.txt")
5. An editable queue of search terms so that the program begins on the next search term once it finishes working on the previous term

File types to handle:
Input: ebook files (.epub, .mobi, .pdf, more if possible)
Output: text files (.doc, .txt, .rtf)

Additional features (optional):
1. set to search multiple specified folders when beginning a search
2. search history tagging files with previously used search terms to prevent duplication in future searches
3. time estimates for completion of search cycle (x min., y sec. to complete search for term)
