I thought that that's the point in the Synonym injection example, setting Term.setPositionIncrement(0) for the injected token(s). That way. phrase queries work since all of the injected tokens share the same offset.... But I've been wrong before. Erick On 5/16/07, Daniel Noll <[EMAIL PROTECTED]> wrote:

I'm not even convinced it would be tricky. I'm fairly sure that if the token stream returns two terms over the same span, that they would have the same start offset and end offset and highlight identically. What *would* be tricky is phrase queries since inserting a new term breaks the offsets AFAIK. Although, I suppose you could always store the concepts in a different field and not modify the analyser being used for the text itself.
