Ask yourself, what is the index in Kyle’s examples indexing?
Kyle says the example are indexing recipes but is that really true?
Or is it the case that the index is indexing the occurrence of a string at a location in the text?
Not exactly the same thing.
That is to say there is a difference between a token that appears in a text and a subject we think about when we see that token.
Interesting point. Basic indexing is dismissing both contextual and semantic attributes. All is left is keywords. Adding back any of contextual or semantic meta will increase results relevancy.
