Koji Thanks a lot it's stopped crashing now. Can I ask one other question about synonym highlighting which looks a bit puzzling?
I enter asset as my criteria and it returns through synonym matching other terms highlighted as well. My debug output is: DEBUG: uk.co.sjp.intranet.service.SolrServiceImpl - Highlighted tag = <em>inves</em>tment DEBUG: uk.co.sjp.intranet.service.SolrServiceImpl - Highlighted tag = <em>asset</em> management DEBUG: uk.co.sjp.intranet.service.SolrServiceImpl - Highlighted tag = <em>inves</em>tment product DEBUG: uk.co.sjp.intranet.service.SolrServiceImpl - Highlighted tag = alternative <em>asset</em>s As you can see asset works well. For the "synonyms" does it just highlight the first n characters where n is the length of the input string? Can't figure out how it could do otherwise.
