Let's say a reviewer for whatever reason wants to compare the item they are reviewing with some other product. When a search is done for THAT OTHER PRODUCT, the first product comes up in the Amazon search results, because, well, I don't know why - they thought (think?) they are being helpful, BUT THEY AREN'T.
Who cares what someone writes in a product review when it comes to product search?
Example: Let's say I am searching for a very specific model or replacement part. I have the manufacturer part number and someone at some time has reviewed SOME OTHER THING and merely mentioned a comparison to the item I am looking for... Now that WRONG part is going to come up in my search result. Do you know how tedious it is to chase down false search results? I friggin' hate that.
