Alan Woodward commented on LUCENE-6494: --------------------------------------- Yeah, it's NearSpansOrdered that makes everything complicated, because by the time you call collect() its child Spans have moved on. So you need to either have just a generic collector type, or pass the collector type to the NearSpansOrdered constructor and have a way of creating a buffered collector from that, which leads to the overcomplicated generics that Robert didn't like. There might be a way of doing this by passing a SpanCollector to the SpanWeight somehow? And just doing some ugly brute-force casting in replay(), risking the ire of the Generics Policeman. But in the meantime, please do try this API out - feedback from people other than me who are using it will be very useful! > Make PayloadSpanUtil apply to other postings information > -------------------------------------------------------- > > Key: LUCENE-6494 > URL: https://issues.apache.org/jira/browse/LUCENE-6494 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Alan Woodward > Assignee: Alan Woodward > Fix For: 5.2 > > Attachments: LUCENE-6494.patch, LUCENE-6494.patch, LUCENE-6494.patch, > LUCENE-6494.patch > > > With the addition of SpanCollectors, we can now get arbitrary postings > information from SpanQueries.
