How to change search component parameters dynamically using query

Hi,

I use the below highlight search component in one of my request handler.

I am trying to figure out a way to change the value of highlight search
component dynamically from the query. Is it possible to modify the
parameters dynamically using the query (without creating another
searchcomponent)?


 <searchComponent class="solr.HighlightComponent" name="highlight">
	<highlighting>
          <boundaryScanner class="solr.highlight.SimpleBoundaryScanner"
default="false" name="simple">
                  <lst name="defaults">
		 	<str name="hl.bs.maxScan">200</str>
			<str name="hl.bs.chars">.</str>
		 </lst>
	    </boundaryScanner>
	    <boundaryScanner class="solr.highlight.BreakIteratorBoundaryScanner"
default="true" name="breakIterator">
	  	  <lst name="defaults">
            	  <str name="hl.bs.type">SENTENCE</str>
                    <str name="hl.bs.language">en</str>
              	  <str name="hl.bs.country">US</str>
              </lst>
           </boundaryScanner>
	</highlighting>

Re: How to change search component parameters dynamically using query

Posted by Erick Erickson <er...@gmail.com>.
Depends on which ones. Any parameter in the "defaults" sections
can be overridden on dynamically, i.e.

.....&hl.bs.language=fr

Best,
Erick
