Examples of no.priv.garshol.duke.databases.LuceneDatabase$EstimateResultTracker

no.priv.garshol.duke.databases.LuceneDatabase
The tracker is used to estimate the size of the query result we should ask Lucene for. This parameter is the single biggest influence on search performance, but setting it too low causes matches to be missed. We therefore try hard to estimate it as correctly as possible. The tracker uses a ring buffer of recent result sizes to estimate the result size.

    config.setProperties(props);
    config.setThreshold(0.45);
    db = new LuceneDatabase();
