Hi all, I need to retrieve query-results with a ranking independent from each query-result's default lucene score, which means assigning the same score to each query result. I tried to use a zero boost factor ( ^0 ) to reset to zero each query-result's score. This strategy seems to work within the "example" solr instance, but in my Solr instance, using a zero boost factor causes a Buffer Exception ( HTTP Status 500 - null java.lang.IllegalArgumentException at java.nio.Buffer.limit(Buffer.java:249) at org.apache.lucene.store.NIOFSDirectory$NIOFSIndexInput.readInternal(NIOFSDirectory.java:123) at org.apache.lucene.store.BufferedIndexInput.refill(BufferedIndexInput.java:157) at org.apache.lucene.store.BufferedIndexInput.readByte(BufferedIndexInput.java:38) at org.apache.lucene.store.IndexInput.readInt(IndexInput.java:70) at org.apache.lucene.store.IndexInput.readLong(IndexInput.java:93) at org.apache.lucene.index.FieldsReader.doc(FieldsReader.java:210) at org.apache.lucene.index.SegmentReader.document(SegmentReader.java:948) at org.apache.lucene.index.DirectoryReader.document(DirectoryReader.java:506) at org.apache.lucene.index.IndexReader.document(IndexReader.java:947) ) Do you know any other technique to reset to some fixed constant value, all the query-result's scores? Each query result should obtain the same score. Any suggestion?
