Forgive my brevity, typos, and poor writing as I'm writing this on my phone. He is stating that you would never actually search on your primary storage mediums. You would build your search index off the primary storage medium such that when looking up an article you do not search over the primary medium and only search the index and then once the article is found you read from said primary medium.
- dredmorbius 9y agoThis, yes.
- Redoubts 9y agoWell sure, but then you have to crawl though thousands of pieces of physical medium to load the file you want...
- sli 9y agoDo search indexes typically not include an identifier for a given resource? Seems to me that an index would be almost useless without them, as the match itself is more often than not far less useful than the document that contains it. Unless the information you need happens to be in the surrounding blurb. So yeah, I'm not sure why you'd have to "crawl" through physical media when a search index ought to tell you right where your match is located. Is that not the entire point of indexing and searching?
- dredmorbius 9y agoAn index maps a query to a specific item. Say, a file reference within a storage hierarchy or record within a database. (The concepts are fundamentally identical.)
