Query on multivalue field

[Scott Yeadon]

Hi,

I have a variable number of text-based fields associated with each 
primary record which I wanted to apply a search across. I wanted to 
avoid the use of dynamic fields if possible or having to create a 
different document type in the index (as the app is based around the 
primary record and different views mean a lot of work to revamp 
pagination etc).

So, is there a way to apply a query to each value of a multivalued field 
or is it always treated as a "single" field from a query perspective?

Thanks.

Scott.
