Subject Re: Innerjoin streaming expressions - Invalid JoinStream error
Date Tue, 18 Apr 2017 13:28:49 GMT
Hi,

I reply to myself

I just had to invert the "on" clause to make it work

curl --data-urlencode 'expr=innerJoin(
                                search(books,
                                   q="*:*",
                                   fl="id",
                                   sort="id asc"),
                                searchreviews,
                                   q="*:*",
                                   fl="id_book_s",
                                   sort="id_book_s asc"),
                                on="id_books_s=id"
                            )' http://localhost:8983/solr/books/stream




{
  "result-set": {
    "docs": [
      {
        "title_s": "The Way of Kings",
        "pubyear_i": 2010,
        "stars_i": 5,
        "id": "book1",
        "id_book_s": "book1",
        "review_dt": "2015-01-03T14:30:00Z"
      },
      {
        "title_s": "The Way of Kings",
        "pubyear_i": 2010,
        "stars_i": 3,
        "id": "book1",
        "id_book_s": "book1",
        "review_dt": "2014-03-15T12:00:00Z"
      },
      {
        "title_s": "The Way of Kings",
        "pubyear_i": 2010,
        "stars_i": 4,
        "id": "book1",
        "id_book_s": "book1",
        "review_dt": "2014-12-15T12:00:00Z"
      },
      {
        "title_s": "Friends",
        "pubyear_i": 1994,
        "stars_i": 5,
        "id": "book2",
        "id_book_s": "book2",
        "review_dt": "1995-01-03T14:30:00Z"
      },
      {
        "title_s": "Friends",
        "pubyear_i": 1994,
        "stars_i": 3,
        "id": "book2",
        "id_book_s": "book2",
        "review_dt": "1994-03-15T12:00:00Z"
      },
      {
        "title_s": "Friends",
        "pubyear_i": 1994,
        "stars_i": 4,
        "id": "book2",
        "id_book_s": "book2",
        "review_dt": "1994-12-15T12:00:00Z"
      },
      {
        "EOF": true,
        "RESPONSE_TIME": 35
      }
    ]
  }
}


However, I don't understand the reason as in debug mode I see
the isValidTupleOrder method should return true in both case.

Regards.

Dominique
