| <div class="markdown level0 summary"><p>Expert: Calculate query weights and build query scorers. |
| <p> |
| The purpose of <a class="xref" href="Lucene.Net.Search.Weight.html">Weight</a> is to ensure searching does not modify a |
| <a class="xref" href="Lucene.Net.Search.Query.html">Query</a>, so that a <a class="xref" href="Lucene.Net.Search.Query.html">Query</a> instance can be reused. |
| <p> |
| <a class="xref" href="Lucene.Net.Search.IndexSearcher.html">IndexSearcher</a> dependent state of the query should reside in the |
| <a class="xref" href="Lucene.Net.Search.Weight.html">Weight</a>. |
| <p> |
| <a class="xref" href="Lucene.Net.Index.AtomicReader.html">AtomicReader</a> dependent state should reside in the <a class="xref" href="Lucene.Net.Search.Scorer.html">Scorer</a>. |
| <p> |
| Since <a class="xref" href="Lucene.Net.Search.Weight.html">Weight</a> creates <a class="xref" href="Lucene.Net.Search.Scorer.html">Scorer</a> instances for a given |
| <a class="xref" href="Lucene.Net.Index.AtomicReaderContext.html">AtomicReaderContext</a> (<a class="xref" href="Lucene.Net.Search.Weight.html#Lucene_Net_Search_Weight_GetScorer_Lucene_Net_Index_AtomicReaderContext_Lucene_Net_Util_IBits_">GetScorer(AtomicReaderContext, IBits)</a>) |
| callers must maintain the relationship between the searcher's top-level |
| <a class="xref" href="Lucene.Net.Index.IndexReaderContext.html">IndexReaderContext</a> and the context used to create a <a class="xref" href="Lucene.Net.Search.Scorer.html">Scorer</a>. |
| <p> |
| A <a class="xref" href="Lucene.Net.Search.Weight.html">Weight</a> is used in the following way: |
| <ol><li>A <a class="xref" href="Lucene.Net.Search.Weight.html">Weight</a> is constructed by a top-level query, given a |
| <a class="xref" href="Lucene.Net.Search.IndexSearcher.html">IndexSearcher</a> (<a class="xref" href="Lucene.Net.Search.Query.html#Lucene_Net_Search_Query_CreateWeight_Lucene_Net_Search_IndexSearcher_">CreateWeight(IndexSearcher)</a>).</li><li>The <a class="xref" href="Lucene.Net.Search.Weight.html#Lucene_Net_Search_Weight_GetValueForNormalization">GetValueForNormalization()</a> method is called on the |
| <a class="xref" href="Lucene.Net.Search.Weight.html">Weight</a> to compute the query normalization factor |
| <a class="xref" href="Lucene.Net.Search.Similarities.Similarity.html#Lucene_Net_Search_Similarities_Similarity_QueryNorm_System_Single_">QueryNorm(Single)</a> of the query clauses contained in the |
| query.</li><li>The query normalization factor is passed to <a class="xref" href="Lucene.Net.Search.Weight.html#Lucene_Net_Search_Weight_Normalize_System_Single_System_Single_">Normalize(Single, Single)</a>. At |
| this point the weighting is complete.</li><li>A <a class="xref" href="Lucene.Net.Search.Scorer.html">Scorer</a> is constructed by |
| <a class="xref" href="Lucene.Net.Search.Weight.html#Lucene_Net_Search_Weight_GetScorer_Lucene_Net_Index_AtomicReaderContext_Lucene_Net_Util_IBits_">GetScorer(AtomicReaderContext, IBits)</a>.</li></ol> |
