Basically you need to use a copyField, but in several variants: If you use the field _exclusively_ for highlighting then store the raw content there and have the field use whatever analyzer you want. You do _not_ need to have indexed="true" set for the field if you're highlighting on the fly. So you're searching against field1 (which has indexed="true" stored="false" set) but highlighting against field2 (which has indexed="false" stored="true" set). Of course any time you want to return the contents in a doc your fl needs to specify field2...
The above does not bloat your index at all since the cost of stored="true" indexed="true" is the same as if you use two fields, each with only one option turned on. The second approach if you want to use FastVectorHighlighter or the like is simply to index both fields.
