Web Crawler and Search Engine

A custom web crawler, indexer, and search engine.

Crawler: MultithreadingUtilizes multiple threads to crawl multiple domains in parallel.
Crawler: Stores Web PagesSaves web page content into JSON files to be indexed later.
Crawler: PolitenessAdheres to robots.txt and enforces a minimum delay between requests to the same domain.
Crawler: Pauseable CrawlingAllows crawling to be stopped and resumed at any time without loss of progress.
Crawler: Customizable CrawlingUses a config file to configure seed URLs, allowable domains, and minimum politeness.
Indexer: MultiprocessingUtilizes multiple processes to index multiple web pages at once.
Indexer: Partial IndexingIndexed content is regularly written to files and combined at the end, minimizing memory usage.
Indexer: N-gram IndexingBreaks text into n-grams, enabling more flexible and relevant query matching.
Indexer: Pauseable IndexingAllows indexing to be stopped and resumed at any time without loss of progress.
Indexer: Recursive IndexThe index of tokens is indexed itself, allowing tokens to be looked up faster.
Search: RankingResults are ranked by a combination of keyword frequency and placement in the page content.
