929

931         <doc>
932           <field name="id">1</field>

941    Note: Each document must contain a field which serves as the
942    unique key. This key is used in the returned response to associate
943    an analysis breakdown to the analyzed document.
944
945    Like the FieldAnalysisRequestHandler, this handler also supports

947    request parameter that holds the query text to be analyzed. It
948    also supports the "analysis.showmatch" parameter which when set to

1030       instances of SearchHandler (which can access them by name)
1031       
1032       By default, the following components are available:
1033       
1034       <searchComponent name="query"     class="solr.QueryComponent" />
1035       <searchComponent name="facet"     class="solr.FacetComponent" />

1037       <searchComponent name="highlight" class="solr.HighlightComponent" />
1038       <searchComponent name="stats"     class="solr.StatsComponent" />
1039       <searchComponent name="debug"     class="solr.DebugComponent" />
1040   
1041       Default configuration in a requestHandler would look like:
1042
1043       <arr name="components">
1044         <str>query</str>
1045         <str>facet</str>

1049         <str>debug</str>
1050       </arr>
1051
1052       If you register a searchComponent to one of the standard names,
1053       that will be used instead of the default.
1054
1055       To insert components before or after the 'standard' components, use:
1056   
1057       <arr name="first-components">
1058         <str>myFirstComponentName</str>

1062         <str>myLastComponentName</str>
