Pypdf Seekers 0.1.3 | GitLocker.com Product

Description:

pypdfseekers 0.1.3

PDF Seekers

Simple parser and information extractor from PDF documents based on keyword search functionality (powered by Rust)

Key Features:

Indexing capability on single PDF file or directory containing multiple PDF files
Search for keywords across multiple PDF files to get relevant information
Get number of pages in PDF file, the page numbers containing the search term, and surrounding text aroung the search term

Python
Installation
Install the latest pypdf-seekers version with:
pip install pypdf-seekers
Releases happen quite often (weekly / every few days) at the moment, so updating polars regularly to get the latest bugfixes / features might not be a bad idea.
Usage Examples
>>> import pypdf_seekers as ps
>>>
>>> data_dir = "data"
>>> cache_dir = None
>>> display_logs = True
>>> search_term = "convolutional"
>>>
>>> ps.indexing_contents(data_dir, cache_dir, display_logs)
