Sorry, hit the Send button too early... foreach (var value in fieldValues) { var fld = new Field("SomeName", value, Field.Store.NO/YES<http://field.store.no/YES>, Field.Index.TOKENIZED/UN_TOKENIZED); doc.Add(fld); }
In the code above the name is the same, only the value changes. There are a couple of things you need to know: 1. For the purposes of search, the code above is the same as var fld = new Field("SomeName SomeName SomeName SomeName SomeName", value, Field.Store.NO/YES <http://field.store.no/YES>, Field.Index.TOKENIZED); provided you use a whitespace or any other tokenizer that treats whitespace as a token separator. It's important to know this if you are planning to use SpanQuery where position of terms makes a difference 2. I mainly use the method for fields that are not tokenized to save index time on tokenization. my 2c worth...
