Hi, Erick! And thank you for answering! You always answer my questions, :-) Well, I´ll try to explain better, because the context is more complex. The original problem becomes from MoreLikeThis behaviour. As you probably know that Solr feature only suggests similar components by the first - and only - document returned from the original query. That is if you have a query that returns 5 documents (a query with five IDs with OR boolean clauses, like before) MoreLikeThis only returns similar documents for the first one.
Thats very frustrating, and I tried to solve it partially - and not very efficiently. I´ve got an intermediate business logic that manages querys from the front-end and Solr architecture. This components defines and API of queries and pre and post processors to execute with it. The thing is that I want to return similar documents for, for example, five documents queried. Due to MoreLikeThis limitations I do this: 1. First MoreLikeThis query for the first document. I get all the similar documents. 2. Second MoreLikeThis query for the second document. I get all the similar documents. ... 5. Fith MoreLikeThis query for the fith document. I get all the similar documents. I have to notice that the order of the query is important. I mean that the first ID is the first ID because its more important that the second ID, etc. So now I have to merge the results but, hey! Imagine that you receive a sort by Date. You have to compose the final response with the merged similar documents and sort it by Date. Thats a problem, right? So I do the following: 1. Get first similar document ID from the first ID response. 2. Get the first similar document ID from the second ID response. ... 3. Get the first similar document ID from the fith ID response. 4. Get the second similar document ID from the first ID response. .... N. Get the N similar document ID from the fith ID response. The number of documents is not important. Imagine that you have a rows=20, so N=20 and you have and array of 20 similar components ordered correctly from most important to less important. Returning to the sorting problem, if you launch another and final query to Solr with q=(all the similar document IDs ordered) you can append the original sorting by Date, so the results can be sorted by Date, or by other field, or just without order... and that´s the problem! If you don´t indicate any order I hope that the documents will be returned with the similar documents IDs sorting: I mean from most important to less important, and you saw what Solr does: returns the documents response with score sort. Phew! And that´s all. Ehm... any suggestion? :-D Hehehe. Thank you so much! Luis Cappa.
