Is Running the Same Filters on Index and Query Redundant?

[Zimmermann, Thomas]

Hi,

We have the text field below configured on fields that are both stored and 
indexed. It seems to me that applying the same filters on both index and query 
would be redundant, and perhaps a waste of processing on the retrieval side if 
the filter work was already done on the index side. Is this a fair statement to 
make? Should I only be applying filters on one end of the transaction?

Thanks,
TZ
