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...
