What is the purpose of a search engine indexer?
Indexing is the process by which search engines organise information before a search to enable super-fast responses to queries. Searching through individual pages for keywords and topics would be a very slow process for search engines to identify relevant information.
How is a search index created?

How is an inverted index used in a search engine?
To summarize, an inverted index is a data structure that we build while parsing the documents that we are going to answer the search queries on. Given a query, we use the index to return the list of documents relevant for this query. The inverted index contains mappings from terms (words)…
How much storage is needed for a search engine index?
Given this scenario, an uncompressed index (assuming a non- conflated, simple, index) for 2 billion web pages would need to store 500 billion word entries. At 1 byte per character, or 5 bytes per word, this would require 2500 gigabytes of storage space alone.
How long does it take a search engine to index a document?
Without an index, the search engine would scan every document in the corpus, which would require considerable time and computing power. For example, while an index of 10,000 documents can be queried within milliseconds, a sequential scan of every word in 10,000 large documents could take hours.
