Search implementation with tokenization

[usirin]

• Search form is used for searching Stack Templates.

• The query in the input should be weighted by following priority list (the item on top is most important) 1) Stack template slug 2) Stack template title 3) Stack template description / readme 4) Template content

• Search query can be filtered via tags (a tag can be represented as <tag-name>:<tag-value>):

  • from:@<username>
  • provider:<provider-slug>
  • example: from:@cihangir provider:aws react

UPDATE:

Depending on https://github.com/koding/kdio/issues/12#issuecomment-281158382 and https://github.com/koding/kdio/issues/12#issuecomment-281158237 the following case should work:

by:cihangir provider:aws golang-server

i don't think @ is necessary for from:@sinan

[sinan]

also instead of from:, by: would be more meaningful

I think we can also add ~clone count~, build count to priority list.
