dismax request handler will give wrong result in solr 4.3

[Viresh Modi]

When i use dismax query type handler in *SOLR 1.4 *and then same for *SOLR
4.3 *then both give different numFound record both have same index profile
as well.
means Solr 1.4 gives 9 records
    and Solr 4.3 gives  99 records.

*My Query is:*

start=0&rows=10&hl=true&hl.fl=content&qt=dismax
&q=system admin
&fl=id,application,timestamp,name,score,metaData,metaDataDate
&fq=application:PunitR3_8
&fq= NOT ( id:OnlineR3_8_page_410_0 OR id:OnlineR3_8_page_411_0 OR
id:OnlineR3_8_page_628_0 )
&fq=(metaData:channelId/100 OR metaData:channelId/10 OR
metaData:channelId/160 OR  metaData:channelId/12)&sort=score desc

*and In Solr Config.xml has handler::*

<requestHandler name="dismax" class="solr.SearchHandler"  default="true">
    <lst name="defaults">
     <str name="defType">dismax</str>
     <str name="echoParams">explicit</str>
     <str name="qf">
         content name
     </str>
     <int name="qs">1000</int>
     <!-- example highlighter config, enable per-query with hl=true -->
     <str name="hl">true</str>
     <str name="hl.fl">content</str>
     <!-- for this field, we want no fragmenting, just highlighting -->
     <str name="f.content.hl.fragsize">150</str>
     <!-- instructs Solr to return the field itself if no query terms are
          found -->
     <str name="f.name.hl.alternateField">name</str>
     <str name="f.text.hl.fragmenter">regex</str> <!-- defined below -->
    </lst>
  </requestHandler>
