Detailed Description

This class supports searching multiple indexes and getting a list of results for each of those indexes.

Each index is expected to have a parameter file that tells where its located and which retrieval method to use, similar to parameter files used for TextRetrievalMethods. If no particular RetrievalMethod is specified, a default one will be used (originally set to Okapi

Member Function Documentation

void lemur::distrib::DistSearchMethod::doSingleRetr (   )  [protected]

assuming all required parameters for index and retrieval method are on the top stack, do retrieval on this single index using the given query.

void lemur::distrib::DistSearchMethod::indexToID (  const lemur::api::Index *  ind, const lemur::api::IndexedRealVector *  ivec, DocScoreVector *  dvec )  [static]

convert the given IndexRealVector into a DocScoreVector.

void lemur::distrib::DistSearchMethod::scoreIndexSet (  const lemur::api::Query &  qry, const vector< string > &  indexset, DocScoreVector **  results )

score every document in each index in the indexset for the given query and return results in the results vector

void lemur::distrib::DistSearchMethod::scoreIndexSet (  const lemur::api::Query &  qry, const lemur::api::IndexedRealVector &  indexset, DocScoreVector **  results )

score every document in each index in the indexset for the given query and return results in the results vector although the scores in indexset probably won't be used, take an IndexedRealVector here because that's what's returned by the RetrievalMethod so would make writing code easier. the indexes in indexset should correspond to indexes in the collection selection index.

void lemur::distrib::DistSearchMethod::setDefaultRetMethod (  lemur::api::RetMethodManager::RetModel  rt  )  [inline]

use the given retrieval method to do search if none is specified for an index

void lemur::distrib::DistSearchMethod::setIndex (  const lemur::api::Index *  index  )  [inline]

use the given collection selection index

void lemur::distrib::DistSearchMethod::setReturnCount (  int  retCount  )  [inline]

set the return documents number;
