grabHits

public void grabHits(SearchResultHits hits,
                     AMIndexSearcher searcher,
                     MBaseRef mbaseRef,

                     List learningContexts)
              throws MBaseException

Goes through the hits and grabs the ones that'll be kept.

Parameters:

hits - lucene-hits out of which one will obtain IDs, score etc...

mbaseRef - used to apply the learner-symbol-policy

applyLearnerSymbolPolicy - wether to apply it or not, this policy states that no symbols should be presented to a learner but, instead, only its definitions, sorted by learning-context

Throws:

MBaseException

gotoNextPage

public void gotoNextPage()

gotoPreviousPage

public void gotoPreviousPage()

moveTo

public void moveTo(int newResultsFrom)
