Queries vs. Filters

Question

I can\'t see any description of when I should use a query or a filter or some combination of the two. What is the difference between them? Can anyone please explain?

Answer 1

The difference is simple: filters are cached and don't influence the score, therefore faster than queries. Have a look here too. Let's say a query is usually something that the users type and pretty much unpredictable, while filters help users narrowing down the search results , for example using facets.
