             FacetResult fres)
               throws IOException

Alter the input result, fixing it to account for the sampling. This implementation can compute accurate or estimated counts for the sampled facets. For example, a faster correction could just multiply by a compensating factor.

Parameters:

origDocIds - full set of matching documents.

fres - sample result to be fixed.

Throws:

IOException - If there is a low-level I/O error.
