轮胎宝石的搜索方法有哪些参数？

Question

I need to run a search using Tire with my query specifically defined as a parameter, but I'm unsure how to proceed.

search = {
  query: {
    function_score: {
      query: { match_all: {} },
      # filters is an array previously built
      functions: filters,
      score_mode: "total"
    }
  }
}

Program.tire.search(load: true, size: 50, search)

I'm receiving the following error: /Users/app/models/program_match.rb:122: syntax error, unexpected ')', expecting tASSOC which makes me believe I'm simply missing a key word before I call search .

Any help would be greatly appreciated!

Answer 1

You probably just need to do:

 Program.tire.search({load: true, size: 50}.merge(search)) 

EDIT

Actually, looking at the source for search ( https://github.com/karmi/retire/blob/master/lib/tire/model/search.rb ), it looks like you need to do:

Program.tire.search(search, {load: true, size: 50})

search expects two params (query, options) or one param (for options) and a block (for the query). Ruby gets confused because you have started a hash ( load: true ... ) and then just put a new hash (your search hash), which it sees as a hash key (with no value).

Also, if you are just starting out with Tire, I would suggest checking out elasticsearch-rails , which, according to the author, is replacing Tire.

I recently converted a Tire project to elasticsearch-rails, and have found that it can do everything Tire does, although it doesn't provide the query DSL (it seems like you're not using that anyway, so no loss).

EDIT 2

You can do a simple match_all query like:

Program.tire.search(load: true, size: 50) { query { all } }

You can get something similar by doing:

Program.tire.search('*', load: true, size: 50)

As I noted in a comment below, a query as the first param for search will always be wrapped in a query_string query.

Probably the best way to do what you asked initially is to do:

Tire.search(Video.tire.index_name, query: {
  function_score: {
    query: { match_all: {} },
    functions: filters,
    score_mode: "total"
  }
}).results

I just tested a similar function_score query on a local project and confirmed that it produces the expected query.

EDIT 3

I've never used the load option before, but it looks like you can do:

Tire.search(Video.tire.index_name, payload: {
  query: {
    function_score: {
      query: { match_all: {} },
      functions: filters,
      score_mode: "total"
    }
  }
}, load: true).results

Note that you have to wrap the query as the value for payload .
