Hello, I'm trying to implement a "Related Articles" feature within my search application using the mlt handler.
To give you a little background information, my Solr index contains a single core that is created by merging 10+ other cores. Within this core is my main data item known as an "article"; however, there are other data items like "technical documents", "tickets", etc. When a user opens an article on my web application, I want to show "Related Articles" based on 2 fields (title and body). I am using SolrJ as a back-end for this . The way I'm thinking of doing it is to search on the title of the existing article, and hope that the first hit is that actual article. This works in most of the cases, but occasionally it grabs either the wrong article or a different type of data item altogether (the first hit my be a technical document, which is totally unrelated to articles). The following is my query: ?qt=%2Fmlt&mlt.match.include=true&mlt.mindf=1&mlt.mintf=1&mlt.fl=title,body&q=<search string>&fq=dataItem:article&debugQuery=true There is one main thing that I noticed is that this only seems to match on the "body" field and not the "title" field. I think it's doing what it's supposed to and I'm not fully grasping the idea of mlt. So when it does the initial search to find the document against which it will find related articles, what search handlers would it use? Normally, my queries are carried out using dismax with some boosting functionality applied to them. When I use the standard query handler however, with the qt parameter defining mlt, what happens for the initial search? Also, if anybody can suggest an alternative implementation to this I would greatly appreciate it. Like I said, it's entirely possible that I don't fully understand mlt and it's causing me to implement stuff in a weird way.
