I also have two fields, one for indexing and another for display. How does the above affect searching? If you type "brown do" will it find the title correctly or do you have to type "brown dog" in order to get a match? Would "brown do" match "The brown horse has a dog" or not? My understanding is that that Lucene (BTW, I'm using 2.4.1 because it's the latest version to work with Compass) matches the prefix first, and then combines the matching results with other clauses as specified. > So as the user is typing we are looking up using a PrefixQuery against the titlekeyword field.

Why did you choose not to use this approach? Is it because of the other things you want to do with those fields or something about the way the SpanQuery classes work? If you are at liberty to share part of your code I'd appreciated it.
