Roland -
Is it possible that you indexed with a different field type and then changed to
"string" without reindexing? A query on a string will only match literally
the exact value (barring any wildcard/regex syntax), so something is fishy with
your example. Your query example was odd, not sure if you meant it literally,
but given the Word field name the query would be q={!term f=Word}apple - maybe
you thought "term" was meta, but it is meant literally here.
