I'm having trouble with query_by_weights. I have 3 code fields (barcode, SKU, manfacturer_number) and I want to search all 3 equally. But even if I use query_by_weights with equal values, I get results for exact matches of earlier items. Product 1: • SKU: 12345 • MFR#: [some string] • Barcode: [some string] Product 2: • SKU: [some string] • MFR#: 12345 • Barcode: [some string] In that example if I search for "12345" and have "query_by=sku, mfr#, barcode" and "query_by_weights=100,100,100" I still get back just 1 hit for Product 1. If I make the weights "100,120,100" then I get 1 hit for Product 2. Based in the documentation, I expected that equal weights would return both items since they're both an exact match. Is there some other nuance I need to account for, or some bug?
