                                   Site site,
                                   Application application,

Description copied from interface: SearchProvider

Performs the actual search

Specified by:

doSearch in interface SearchProvider

Parameters:

env - the current Environment

site - the current Site

application - the current Application

directory - the Directory representing the current Site's Lucene index.
Note that it only makes sense to use this directory for searching if the Application also contributes some Documents to the Site's global index by using FeatureProvider.getIndexer() or implementing DocumentProvider. Otherwise, the Application might have it's own Lucene index or even get the Documents from somewhere else (for example from the database or filesystem).

term - the search term

language - the language for the search

parseFields - the fields to search

analyzer - the Analyzer to use

highlightWith - a tagname to highlight fragments with, e.g span or div

parameters - some custom parameters for this search

Returns:

an Iterable<Document> containing the found Documents

Throws:

IOException - if an error occurs while searching

getQuery

protected org.apache.lucene.search.Query getQuery(String[] parseFields,
                                                  String searchTerm,
                                                  org.apache.lucene.analysis.Analyzer analyzer,
                                                  String language,
                                                  String[] excludeTypes)
                                           throws org.apache.lucene.queryparser.classic.ParseException

Throws:
