Question

There reason I ask is that I had been using the strongly typed version, but ran into the issue of it not being flexible enough, so I switched over to the AdvancedQuery.Luncene which did provide the flexibility but at a loss in performance. I was thinking that the lower level query engine would be faster than than it counter-part or at least equivalent. Can someone shed some light on this?

Thank you,
Stephen

watch = Stopwatch.StartNew();
        result = s.Query<Product>()
            .Statistics(out stats)
            .Where(x => x.HasPicture == true)
            .ToArray();
watch.Stop();

Time elapsed to execute query for HasPicture == true 975

Total number of products found: 412352

watch = Stopwatch.StartNew();
result = s.Advanced.LuceneQuery<Product>("Products_Index")
            .Statistics(out stats)
            .Where("HasPicture:(True)")
            .ToArray()
            ;

watch.Stop();

Time elapsed to execute query with Lucene 7065

Total number of products found: 412352

Thanks to Itamar.

The problem was the Where clause, when using the LuceneQuery use WhereEquals.

 result = s.Advanced.LuceneQuery<Product>("Products_Index")
                    .Statistics(out stats)
                    .WhereEquals("HasPicture", true)
                    .ToArray()
                    ;
