Method Summary

static void	doPagingSearch(java.io.BufferedReader in, org.apache.lucene.search.Searcher searcher, org.apache.lucene.search.Query query, int hitsPerPage, boolean raw, boolean interactive) This demonstrates a typical paging search scenario, where the search engine presents pages of size n to the user.
static void	doStreamingSearch(org.apache.lucene.search.Searcher searcher, org.apache.lucene.search.Query query) This method uses a custom HitCollector implementation which simply prints out the docId and score of every matching document.

Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Simple command-line based search demo.

Throws:

java.lang.Exception

doStreamingSearch

public static void doStreamingSearch(org.apache.lucene.search.Searcher searcher,
                                     org.apache.lucene.search.Query query)
                              throws java.io.IOException

This method uses a custom HitCollector implementation which simply prints out the docId and score of every matching document. This simulates the streaming search use case, where all hits are supposed to be processed, regardless of their relevance.

Throws:

java.io.IOException

doPagingSearch

public static void doPagingSearch(java.io.BufferedReader in,
                                  org.apache.lucene.search.Searcher searcher,
                                  org.apache.lucene.search.Query query,
                                  int hitsPerPage,
                                  boolean raw,
                                  boolean interactive)
                           throws java.io.IOException

This demonstrates a typical paging search scenario, where the search engine presents pages of size n to the user. The user can then go to the next page if interested in the next hits. When the query is executed for the first time, then only enough results are collected to fill 5 result pages. If the user wants to page beyond this limit, then the query is executed another time and all hits are collected.

Throws:

java.io.IOException
