EarlyTerminatingCollectorException in MLT Komponente von SOLR 4.4

Question

Ich sende eine Anfrage an SOLR, die genau ein Dokument zurückgibt. Es ist eine "id: some_doc_id" Suche. Hier sind die Parameter wie in der Reaktion gezeigt:

params: { 
mlt.mindf: "1", 
mlt.count: "5", 
mlt.fl: "text", 
fl: "id,,application_id,... project_start,project_end,project_title,score", 
start: "0", 
q: "id:some_doc_id", 
mlt.mintf: "1", 
mlt: "true", 
wt: "json", 
rows: "1" 
} 

Der reponse Schlüssel enthält das Dokument ich erwartet habe, aber ich habe auch einen Fehler, der in der MLT-Komponente zu passieren scheint. Hier ist der Stack-Trace in der Antwort zur Verfügung gestellt:

Mein Code hat gut funktioniert, bevor das Update auf SOLR 4.4. Irgendein Hinweis, was los ist und wie man es löst?

Answer 1

von EarlyTerminatingCollector Geworfen, wenn die maximalen die Torreigen/Sammelprozess frühzeitig abzubrechen, wenn die angegebene maximale Anzahl von Dokumenten gesammelt wurde.

Diese Beschreibung klingt nicht wie eine echte Ausnahme und eher wie eine Art und Weise das Sammeln von Dokumenten abzubrechen.

@Override  
public void collect(int doc) throws IOException {  
    delegate.collect(doc);  
    lastDocId = doc;   
    numCollected++;  
    if(numCollected==maxDocsToCollect) {  
     throw new EarlyTerminatingCollectorException(numCollected, lastDocId);  
    }  
}
