I have no experience with highlighting, but I think the reason that this happens is because of how the Lucene index (specifically in this case, the EdgeNGram filter) stores information in the index. I put your fieldType into a 6.2 example index and did index analysis on "computer". This is the result: https://www.dropbox.com/s/ph524b8ij1hk28o/solr-analysis-computer-edgengrams.png?dl=0 Notice how every term has a start value of "0" and an end value of "8" ... this is the character position inside the original indexed text. Every term resolves to the original source text of "computer". I believe these start/end values in the index are how highlighting decides *what* to highlight, though I admit I could have a flawed understanding of how it works. If my understanding is correct, then obtaining what you want would involve an alternate NGram filter that writes different start/end values. I'm don't think that an alternative like this to EdgeNGram exists. Thanks, Shawn
