Java Source Code / Java Documentation » Net » lucene connector » org.apache.lucene.search   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.apache.lucene.search.Searcher       org.apache.lucene.search.MultiSearcher All known Subclasses:   org.apache.lucene.search.ParallelMultiSearcher, MultiSearcher public class MultiSearcher extends Searcher (Code) Implements search over a set of Searchables. Applications usually need only call the inherited MultiSearcher.search(Query) or MultiSearcher.search(Query,Filter) methods. Constructor Summary public   MultiSearcher(Searchable[] searchables)      Creates a searcher which searches searchables. Method Summary public  void close()      protected  Weight createWeight(Query original)      Create weight in multiple index scenario. Distributed query processing is done in the following steps: 1. public  Document doc(int n)      public  Document doc(int n, FieldSelector fieldSelector)      public  int docFreq(Term term)      public  Explanation explain(Weight weight, int doc)      public  Searchable[] getSearchables()      Return the array of Searchable s this searches. protected  int[] getStarts()      public  int maxDoc()      public  Query rewrite(Query original)      public  TopDocs search(Weight weight, Filter filter, int nDocs)      public  TopFieldDocs search(Weight weight, Filter filter, int n, Sort sort)      public  void search(Weight weight, Filter filter, HitCollector results)      public  int subDoc(int n)      Returns the document number of document n within its sub-index. public  int subSearcher(int n)      Returns index of the searcher for document n in the array used to construct this searcher. Constructor Detail MultiSearcher public MultiSearcher(Searchable[] searchables) throws IOException(Code) Creates a searcher which searches searchables. Method Detail close public void close() throws IOException(Code) createWeight protected Weight createWeight(Query original) throws IOException(Code) Create weight in multiple index scenario. Distributed query processing is done in the following steps: 1. rewrite query 2. extract necessary terms 3. collect dfs for these terms from the Searchables 4. create query weight using aggregate dfs. 5. distribute that weight to Searchables 6. merge results Steps 1-4 are done here, 5+6 in the search() methods rewritten queries doc public Document doc(int n) throws CorruptIndexException, IOException(Code) doc public Document doc(int n, FieldSelector fieldSelector) throws CorruptIndexException, IOException(Code) docFreq public int docFreq(Term term) throws IOException(Code) explain public Explanation explain(Weight weight, int doc) throws IOException(Code) getSearchables public Searchable[] getSearchables()(Code) Return the array of Searchable s this searches. getStarts protected int[] getStarts()(Code) maxDoc public int maxDoc() throws IOException(Code) rewrite public Query rewrite(Query original) throws IOException(Code) search public TopDocs search(Weight weight, Filter filter, int nDocs) throws IOException(Code) search public TopFieldDocs search(Weight weight, Filter filter, int n, Sort sort) throws IOException(Code) search public void search(Weight weight, Filter filter, HitCollector results) throws IOException(Code) subDoc public int subDoc(int n)(Code) Returns the document number of document n within its sub-index. subSearcher public int subSearcher(int n)(Code) Returns index of the searcher for document n in the array used to construct this searcher.
