Considering Lucene level every term in the document field is attributed by positions (if you don't omit them) i.e. your document looks like ["red"@0, "redder"@1, "reddest"@2,"yellow"@3, "blue"@4] pls check the info PhraseQuery, SpanQueries and positionIncrementGap. I have an experience of obtaining the matched spans (positions) from SpanQueries http://blog.griddynamics.com/2011/10/solr-experience-search-parent-child.html But I suppose you need something much more out-of-the-box. Have you check highlighting support in Solr - it looks like what you need. Unfortunately I've never deal with highlighting.
