Array Value Url Queries
I have written some articles on Solr and even more on AngularJs however when it comes to URL queries, I think a lot of production solutions do the opposite of what I'm about to suggest. I think the simpler approach is better and if major companies looked at their solution might find that their UI to be over cumbersome. I think if a URL is public it should be straightforward with what its values mean. This gives advanced users the ability to directly navigate and novice the ability to bookmark urls.
The problem with facets in search grid is that you have a limited number characters you can use. This is less of a problem in a post form but you won't get link for your novice users. I don't like the idea of a "bookmark button" - style UI where it provides the users with a guid that is unique to their search. So a get method approach is more appropriate for the behavior we want. At one point I thought it would be necessary for guid value kind of system. Where the all facets are set up to a single value and all possible outcomes are based on the number system. However with all my designed I ask WHY, and from the opposition I always hear - "because the users will want it", but how much proof does that really hold? Multiple facets doesn't make a search engine better or easier to understand.
