Thanks Tim and Upayavira for your replies. I still need to decide what the final syntax could be, however generally speaking the ideal would be that I am able to extend the current Lucene syntax with a new expression which will trigger the creation of a more like this query with something like +title:foo +"text for similar docs"%2 where the phrase between quotes will generate a MoreLikeThisQuery on that text if it's followed by the % character (and the number 2 may control the MLT configuration, e.g. min document freq == min term freq = 2), similarly to what it's done for proximity search (not sure about using %, it's just a syntax example). I guess then I'd need to extend the classic query parser, as per Tim's suggestions and I'd assume that if this goes into the classic qp it should be a no brainer on the Solr side. Does it sound correct / feasible?
