: Nov 19, 2007 3:01:31 PM org.apache.solr.core.SolrException log : SEVERE: java.lang.NoSuchMethodError: : org.apache.lucene.search.BooleanQuery.clauses()Ljava/util/List; : at org.apache.solr.search.QueryUtils.isNegative(QueryUtils.java:38)
that's a pretty gnarly exception. unless there was an earlier exception you aren't showing us, that suggests that the version of the BooleanQuery class loaded by Solr at runtime isn't the same version it was compiled against. have you odn't anything funky with your classpath? like swap he lucene jar in the solr.war, or put another lucene jar somewhere else in your your classpath when running your servlet container? -Hoss
