Method Detail

run

public void run()

Performs a search over indexes in a Lucene database according to the language with which it was created.

First the indexes, i.e. the collections which are to be searched are determined. Then, for each collection, a search is performed querying the 'title' and 'text' document fields. These two result lists are merged according to the specified weights (titleWeight, textWeight) for the document fields. At the end, all result lists from different collections are merged into one CLEFResultList.
