Depends what you want! Leaving aside what you want back in terms of stored fields, it won't make a huge amount of difference - the words will still be indexed. The main difference I can think of is to do with positionIncrementGap, which is used to influence term positions, which is relevant for phrase queries. Take the following sentences: I like Summer. Sun warms the earth. As a single field, "summer sun" would match as a phrase query. As a multivalued field with a positionIncrementGap of zero, I'm pretty sure "summer sun" would also match. However, with a gap of 100 for a multivalued field, "summer" and "sun" would be considered 101 positions apart - as such they're not next to each other and therefore wouldn't constitute a phrase.
