But again, as Ahmet mentioned… it doesn't look like the surround query parser
is actually being used. The debug output also mentioned the query parser
used, but that part wasn't provided below. One thing to note here, the
surround query parser is not available in 1.4.1. It also looks like you're
surrounding your query with angle brackets, as it says query string is
{!surround}<Contents:"only be">, which is not correct syntax. And one of the
most important things to note here is that the surround query parser does NOT
use the analysis chain of the field, see
<http://wiki.apache.org/solr/SurroundQueryParser#Limitations>. In short,
you're going to have to do some work to get common grams factored into a
surround query (such as maybe calling to the analysis request hander to "parse"
the query before sending it to the surround query parser).
