  HiCoins as reward: 0 (problem unresolved)

ay there are 3 websites in internet.


1) abcd.com/article1


"Internet forum is a place to discuss science and technology"


2) pqrs.com/article2


"Internet forum is an open place for discussion"


3) mnop.com/article3


"Internet forum has many sites where people discuss science and technology openly".


How'd these be indexed?


one


This is the only  information I found for learning about indexing and searching in big data from theoritical point of view. And it's not 100% clear how indexing would happen in big data. I'd appreciate the example with my above websites or any examples you can think of.

Hello, friend!

Similar to dictionaries, train timetables, and book catalogs, indexing is implemented by continuously narrowing the range of data to be obtained to filter out the desired results, and turning events that are originally random queries into ordered events.

An index records a certain order of table records. Therefore, the index itself is usually large and cannot be stored in the memory. The final index is usually stored in the hard disk in the form of a file.

In conclusion, an index can be simply understood as a sorted and fast data search data structure.

Hope this helps!
