Plucene::Search::Filter - phpMan

NAME
    Plucene::Search::Filter - A search filter base class

DESCRIPTION
    This doesn't seem to be being used just yet. But here is some info on
    filters:

    Filtering means imposing additional restriction on the hit list to
    eliminate hits that otherwise would be included in the search results.

    There are two ways to filter hits:

    *   Search Query - in this approach, provide your custom filter object
        to the when you call the search() method. This filter will be called
        exactly once to evaluate every document that resulted in non zero
        score.

    *   Selective Collection - in this approach you perform the regular
        search and when you get back the hit list, collect only those that
        matches your filtering criteria. In this approach, your filter is
        called only for hits that returned by the search method which may be
        only a subset of the non zero matches (useful when evaluating your
        search filter is expensive).
