this plugin was developed for 6.6.0 as mentioned in the description. this won't work with 7.x because overridden method createWeight has changed in 7.x.If you wish to use this 7.x just replace createVectorQuery.java with the following code and create a jar.
package com.github.saaay71.solr;
import java.io.IOException;
import org.apache.lucene.index.LeafReaderContext;
import org.apache.lucene.search.ConstantScoreScorer;
import org.apache.lucene.search.ConstantScoreWeight;
import org.apache.lucene.search.DocIdSetIterator;
import org.apache.lucene.search.IndexSearcher;
import org.apache.lucene.search.Query;
import org.apache.lucene.search.Scorer;
import org.apache.lucene.search.Weight;
public class VectorQuery extends Query {
String queryStr = "";
Query q;
public VectorQuery(Query subQuery) {
this.q = subQuery;
}
public void setQueryString(String queryString){
this.queryStr = queryString;
}
@Override
public Weight createWeight(IndexSearcher searcher, boolean needsScores, float boost) throws IOException {
Weight w;
if(q == null){
w = new ConstantScoreWeight(this, boost) {
@Override
public Scorer scorer(LeafReaderContext context) throws IOException {
return new ConstantScoreScorer(this, score(), DocIdSetIterator.all(context.reader().maxDoc()));
}
@Override
public boolean isCacheable(LeafReaderContext ctx) {
// TODO Auto-generated method stub
return false;
}
};
}else{
w = searcher.createWeight(q, needsScores, boost);
}
return w;
}
@Override
public String toString(String field) {
return queryStr;
}
@Override
public boolean equals(Object other) {
return sameClassAs(other) &&
queryStr.equals(other.toString());
}
@Override
public int hashCode() {
return classHash() ^ queryStr.hashCode();
}
}
I am getting the same error while trying on 8.6. I updated the VectorQuery class with the above code but still, the error persists. Anybody solved this on 8.6?
