[jira] [Comment Edited] (SOLR-788) MoreLikeThis should support distributed search
[ https://issues.apache.org/jira/browse/SOLR-788?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17642847#comment-17642847 ]

----------------------------------------------------------------
it boils down to design question: how to respond to query coordinator with boosted terms, and bool occur (I think it's necessary to pass {{-id:PK}} as well). Here are the options:
# put terms into NamedList (or MapWriter)
# encode Bool,Term, Boost queries via NamedList
The former option is a little bit problematic since lucene's MLT yields queries not terms, I'd rather change it to make some methods public. The later option, might be a foundation for important mechanic which Solr lacks so far.
Which one to choose, wdyt?
