OpenGenus Quark: World's first Offline Search Engine

This is the World's first Offline code Search Engine presented by OpenGenus Foundation. You can, now, search code for any algorithm or data-structure in your favorite language even when you are not connected to the internet.

Get your offline code search engine from Chrome Web Store

This wonderful extension empowers you to:

• Save web pages as a single HTML page to your local machine
• Save web pages in your browser for offline reading
• Analyse your web history safely
• Play games while offline
• Browse for images while offline
• Search for any code for any algorithm or data-structure in your favorite language even when you are not connected to the internet

We are on a mission to bring the best parts of the Internet Offline, enable people to work offline for a longer period of time and revolutionize the way people interact with the web.

"We made the internet and it made us vulnerable. We fought and we won."

The best part is that the massive effort put to build this awesome search engine is open to all. Yes, we are an open-source organization and over 1000 people have become an integral part of our family in our ambitious journey. You can help us too.

Enjoy this tweet by David Heinemeier Hansson:

How can one search bubble sort if there is no internet? The solution is OpenGenus Quark.

Contribute

We love new family members. We encourage you to discuss with us on how can you help us, take up and solve an issue and revolutionize the World irrespective of your experience or knowledge. We keep things simple, so, that everyone on our planet can contribute to this Offline Mission and we are, always, ready to help you out.

Over 700 people left a mark in history by becoming an OpenGenus family member. You are next.

Filtered search results are not shown

This is a(n):

• New feature proposal
• Reporting a keyword
• Error
• Proposal to the Search Engine
• Other

Directory indexing for creating search database

This is a(n):

• New feature proposal
• Reporting a keyword
• Error
• Proposal to the Search Engine
• Other

Details:

Currently all the search database is stored in obj. All the search entries are hard-coded in popup.js. It seems both unscalable and tedious to maintain for large search entries.

1. It can be replaced with directory indexing.
2. The chrome extension will create initial search database by directory indexing.
3. Whenever a new update is made to the directories, it will be reflected in the database instantly after flushing the indexing file.
4. This will ease the process of updating search entries because now we don't have to maintain a hard-coded database and a simple update in the directory will be enough.
