I have implemented PgSearch on my Node model like so:

include PgSearch
pg_search_scope :node_search, against: [:name, :user_id, :circa],
    using: { tsearch: { any_word: true} },
    :associated_against => {
      comments: [:message],
      user: [:first_name, :last_name, :email],
      memberships: [:relation]
    }

And in my controller I have this:

if params[:search]
  @nodes = Node.node_search(params[:search])
end

Ideally, what I would like to be able to do though, is have someone be able to type in the text representation (a flag) of one of the associations and have the search filter just on that flag.

E.g. say: "name: Bouncing Ball", where the search would take place just on the column called name on the nodes model. Aka...it would look for all the nodes with the name Bouncing Ball and not search other columns or models or even any of the associations.

Naturally, I would like to be able to do searches like: owner: John Brown (which searches for all nodes whose owner/user first_name and last_name are John Brown), comment: Manhattan (which searches for all nodes that have a comment with the text Manhattan in the copy, and so on.

How do I achieve this with PgSearch?

  • Can you not do this in the controller, with a regex/string manipulation? For instance just check if 'owner:' exists as part of params[:search], and then just use some conditional logic? – Ralph King May 29 '15 at 09:37
  • @OliverM that sounds interesting. Can you show me a code example. Thanks! – marcamillion May 29 '15 at 20:14
  • Although this seems interesting, but I really doubt that it would affect the performance at all... ( under the assumption that all the columns you search in are properly indexed). I know you didn't mention anything about performance and you most properly need this to filter results only... – a14m May 31 '15 at 02:49

Have you tried to use a combinations of "Dynamic search scopes" with some controller processing of the search string?

name: Bob, parse out the columns/relationship and the searching value then pass it to a pg_search_scope with a lambda block?
