  ...you need to look again, as I have never mentioned anything along that line.  Here it is, in case it was forgotten:
Search for a part where you want to only see cut tape, since that is what you are going to be ordering....instead the results are 3-4 times as long. Why?  Because now it ignores the request to show cut tape parts & also shows 3 or 4 other types. 
So not sure where you came up with that statement.

 It fails to limit to only the cut tape selections when requested.  If you request to see only smd parts & it also shows through hole parts as well, that would be a similar failure.   The various filters are there to reduce the size of the generated listing from 10'000 of  thousands of parts, to maybe a few hundred or dozens.

When one selects to show only cut tape parts, those are the only package style that should be seen.  If you select TO-220 transistors, you should not have TO-92 in its column as well. 

  for example you see an lm324 offered the following ways, with 3 different digikey numbers for 3 different packaging options:
   
LM324MX/NOPBTR-ND      ....Tape & Reel (TR)
LM324MX/NOPBCT-ND  ....Cut Tape (CT)
LM324MX/NOPBDKR-ND    ...Digi-Reel®

When cut tape is selected that is the packaging desired, so which of the above make easy sense to include in the generated listing????  This is where it falls apart.

LM324MX/NOPBCT-ND   ....Cut Tape (CT)  should appear in the listing & the others shouldn't, because those are not cut tape.  ...however the others are not being filtered out, adding to the clutter & length of the listing, requiring more scrolling.

How is it impossible to show only: LM324MX/NOPBCT-ND   ....Cut Tape (CT)  when the cut tape filter is selected???   
It is no more impossible than showing only 100 ohm resistors when that 100 ohm filter is selected !!

If you wanted to see cut tape OR tape and reel in the list, then you would simply select both of those options.

As far as other suppliers having their own numbers, that may be fine, however most purchasers won't even look at the digikey numbers or other supplier numbers. So they may order a 1N914B with an easy chance for mistakes to happen.

I "came up with" that statement because it's what you said, even though it's evident that you meant something altogether different.

You keep insisting that it's showing you products ("parts") that do not meet your criterion, but it's not; it's showing you (additional) packaging options you don't want. But the search doesn't search for packaging options, it's a product search. The product is available as cut tape, ergo, it shows up in the list.


If you search for "LM324", one resulting manufacturer part number is, in your example, LM324MX/NOPB. When you select "cut tape", it removes any LM324s that are not available as cut tape. The three DK part numbers you list show the three packaging options, but cut tape is one of them. You ARE NOT being shown an LM324 that is unavailable as cut tape! Ergo, you are seeing ONLY LM324s that are available as cut tape.

I have addressed the issue of wasted space previously (though you never responded). But let me state it again, since you clearly needs things explained slooooooowly: I agree that also listing the packaging options that you're not interested in wastes space. I understand that what you want is to hide those packaging options. But that's not how the search works, and in the past, it only looked like it did because of how DK listed each packaging option as a separate line item. Now that they're displaying results as products (not packaging options!) as each line item — the way most electronics distributors do it — it's behaving in a way you don't like.

But it's NOT misbehaving in the way your hyperbolic rants suggest, as if it were showing you incorrect products. It is not. It's NOT going to give you the wrong resistor value, or a TO-220 instead of a TO-92.

The search looks for parts that contain a particular characteristic. It doesn't care whether it also has other characteristics. In other words: it behaves like an OR gate. You want it to behave like an XOR gate.

Although I understand the possibility of trouble, I personally don't see the display of all the different packaging types as detrimental to the search results - they are listed as a single hit per manufacturer P/N, as shown in this filtered search. If they were listed at every hit, I would not be really pleased.

Once in the product page, the selection for each part number is not as bad - just a click away. Sure, it can lead to errors, but in my experience the procurement folks tend to send pre-canned lists with exact manufacturer P/Ns exactly to avoid these errors.

I did not add other filters to see if there are gaps, but the specific packaging example does not seem to be too critical.

Thank you, at least you seem to understand what I'm talking about.

eevcandies:
it's showing you (additional) packaging options you don't want. But the search doesn't search for packaging options,

WHY? You are specifying what you want to see for those particular options. What would prevent this from happening?--you seem unable to answer that.
In fact, the particular sku is unimportant when showing the resulting list--you click on the particular displayed item.

Once you select a particular package or packaging you are in effect saying those are the only ones that you wish to see.  Yes, it is available in cut tape & you are telling it that is what you want to to see, no need to show reel, bulk, bag , etc...you are telling it.  Likewise, if you tell it you want to  see 3.865K resistors, it will show list those.

If you look up an LM7807ACXG3 part number that comes from 5 different companies & you select you want to filter out & see only Motorola, it doesn't insist on showing you Intel & RCA, just because the same parts are available from them.  Likewise cut tape can do the same.

Your reply seems to revolve around that's not the way it work/is working. , which is rather problematic.  If it was working as desired, this wouldn't be brought up in the first place.   If a customer raises something as an issue it should be treated is an issue & you seem to prefer debating a shortcoming.  Our new car won't start when it's cold---you don't understand, it has to be warmer for it to start. It doesn't work the way you want.

No, you're not. You're asking it to find the products that contain that particular option.

Think of it like this: Imagine a search for cars. One box lets you choose creature comforts. Let's suppose it lets you select these features:

air conditioning
cooled seats
heated seats
leather trim
simple stereo
fancy navigation stereo
rear-seat child tranquilizer spray


Now, do we agree that while some of these features are mutually exclusive (like the simple stereo vs the fancy navigation stereo), other features can exist in the same car at the same time? (Like you can have a car with heated seats, air conditioning, the fancy stereo, and the child knockout spray.)

Suppose that you're after a car with tranquilizer spray, since you run a daycare and have to chauffeur people's rugrats twice a day. Very few cars have this, so you select the rear-seat child tranquilizer spray feature. Then you click "apply" to see just the cars that have it.

The list now shrinks to the few cars that have that feature. As it turns out, they all have AC, but some have heated seats, some have the fancy stereo, others have the simple one. But they still show up in the list because the feature filter doesn't mean "show me the cars that ONLY have this feature, and no other features".

Similarly, if you want a car with both the rear-seat child tranquilizer spray and a fancy navigation stereo, selecting those features shows only the cars that do have both of those features, regardless of whether they have leather trim or not, or heated seats or not, etc.

In DK's system, packaging functions like a feature: multiple packaging options exist as attributes of a product. (The packaging options are not separate products!!!! The old website displayed them as if they were, but they're not.) So when you click "cut tape", it's eliminating all the parts that don't have a cut tape option. The fact that other packaging options exist simply doesn't matter.

Ultimately, all you're asking for is for options you don't care about to be hidden in the list view.

But it's a fundamentally different type of query, because a (normal) resistor has one and only one resistance value. Consequently, selecting a single value necessarily eliminates every resistor whose value isn't the one you selected.

Yes, because a particular one part can't be made by both Motorola and Intel at the same time. Each one has one, and only one, manufacturer.


--- Quote from: eevcandies on October 15, 2020, 06:52:21 pm ---Likewise cut tape can do the same.
--- End quote ---
No, it's not the same, because each part can have more than one packaging option.

For the third time: I agree that showing every packaging option in the list wastes space. How many more times do I have to say this?!?

What I keep responding to is your very incorrect assumptions about how the system works, what a search even means, and your tone.


Let's look back at the car search analogy: what you are essentially asking for is for the search results list to suppress the leather trim, heated seats, etc. listing from the results because you didn't ask for them and they take up space. This is a legitimate request, though some people might prefer it to work differently. But you keep padding this request in outright false claims, basically saying "I hate how the search wastes space on features I don't care about. The search is so broken! I asked for the child tranquilizer spray, yet it's showing me cars that don't have it!", which is plainly and demonstrably NOT the case!

I wish I could take credit for it! All I did was add the automatic dispenser. :P
