#define MGETTOPDOCSNUM   10

Only use the top n documents retrieved from a database to build the regression model.

#define MINLESSDBPERCEN   0.4

The threshold of backing off to CORI results merging algorithm.

#define MINOVERLAPDOCNUM   3

The minimum number of overlap documents (training data points) for a single databases. Implementation of regression merging method for single database type case (All the individual databases are using Inquery(CORI) retrieval algorithm. Build a single regression model for all the databases. When there is not enough training data, the algorithm backs off to CORI results merging algorithm. Assume all the documents scores have been normalized See RetrievalMethod for database ranking algorithms (CORIRetMethod). See DistSearchMethod for multiple individual database retrieval. See CORIMergeMethod for CORI results merging algorithm
