database - Search engine with ability to search for exact match over multiple views? - suppose have bunch of raw text, on want perform search. example: "* escaped", or "president of united states". as have searched there many tools can (e.g. lucene) indexing many possible n-grams. suppose in add-on raw text (view 1) somehow create view assigning each word lebel = {a, b} view of raw text (view 2). example, if there document containing: view1 = "jack killed john because doesn't know how code" we have view 2, each word: view2 = "a b b b b" (in general might have more views, let's have 2 view) given sec view, want able search combination of 2 views. for example: "a of united states" "president of b" or perhaps explicitly specified: "v2={a} v1={of united states" "v1={president of the} v2={b}" are there similar capabilit

haskell - Is name reuse the only advantage of type classes? - i trying understand type classes in haskell. i pose question using simple example: lets consider 2 datatypes, a , b . lets assume a1 , a2 of type a , b1 , b2 of type b . now let's assume want define functions check if a1 equals a2 , whether b1 same b2 . for have 2 options: option 1: define 2 equality functions using separate names : eqa :: -> -> bool eqa = ... eqb :: b -> b -> bool eqb = ... now if want check if a1 equals a2 write : eqa a1 a2 , b : eqb b1 b2 . option 2: we create a , b instances of eq typeclass. in case can utilize == sign checking equality follows. a1==a2 b1==b2 so, question : far understand sole purpose of existence of type classes can reuse function name == equivalence checking function, shown in alternative 2. if utilize type classes not have utilize different function names same purpose ( i.e. checking equality). is correct? n
