Description

I need to do range search on an integer field, which is defined as type sint. It works fine without highlight. However if I turn on highlight, I got the following error:

2008-02-25 16:54:53,524 ERROR [STDERR] Feb 25, 2008 4:54:53 PM org.apache.solr.core.SolrCore execute

I also tried range strange on data field, got similr error too when use highlight. I posted the problem at solr user list, here is what Hoss said:
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I'm not sure if i really understand what it would mean to highlight a numeric field, hilighting a range query probably won't ever work
because of the way range queries are implemented in Solr ... but at the very least there should be a better error message in this case. (and the
case of a simple single value numeric lookup should probably work)
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The reason I need to highlight the numeric or data field is I have to loop through the search result to apply role permission check on those fields. If the searcher doesn't have permission to see the numeric/date field of the user in the search result list, that field should be set to null when returned. If the search doesn't have permission on all matching fields, then the whole record should not be returned. How can I find out which field is the matching field if searching on multiple fields? The only easy way I can think about is if the field is highlighted, it's a matching field.
