In general, the two ways to compute counts are top-down, by making a separate query for each filter, or bottom-up, by scanning the results and aggregating the counts, like a group-by. Top-down is good for a small universe of values, but bot

BTW, I highly recommend the Relevance Slack as a good space to discuss this and search-related topics generally. It's run by OpenSource Connections, but it's free and anyone can join, even folks who compete with them. It's th

While the acquisition was good for me financially, I agree that Oracle didn't really invest in sustaining Endeca as a product. I am proud of what we achieved at Endeca, but search has come a long way since then. Coincidentally, I now c

I've found that, for mobile screens, the most valuable refinement real estate is often the top row of the results. Since that space is very limited, there's only room for the most useful facets or filters. And you have to decide w

Thanks for the kind words! I'm not usually on HN, but I just discovered this thread and am happy to contribute if I have anything useful to add. The book is a bit dated, but I have continued to post about search more broadly on Medium,

As others have pointed out, most search engines don't support natural language search in general, let alone natural language negation in particular. There are several reasons for this, including the following: 1) Natural language under

Yes, this is real. And she could really use the help. It was very brave of her to come forward this way: she took personal risk, and it's not like she's gaining anything from this personally. On the contrary, she's facing thr

Am curious to see having the dictionary in a trie allows you to build an implementation that is O(n). Will add it to the blog post if it works.

Peter actually emailed me directly, though I was already very familiar with his work on this and similar problems. But yes, I make it very clear in the post (and to candidates) that they should not assume an English -- or even a natural lan

Sorry. The post renders well in Chrome on my Mac and on my Nexus One. But apparently not so well in other browser / platform combinations.

I don't have stats I can share, but I assure you that this problem has confounded many interview candidates with strong resumes. I agree with you that it's all basic material -- that's deliberate. I'm glad you think it's too easy. :-)

Point taken. But it's hard to come up with good interview questions, as my colleagues here, at Google, and at Endeca can attest. In contrast, it's much easier to post solutions. That's why I'm working on an approach that assumes the candida

Sorry about that. Advice on how to fix it while maintaining good rendering elsewhere? Looks good in Chrome on my MacBook and my Nexus One.

Secret is a strong word -- I link to another post on the subject in the article. Still, seeing it on Glassdoor for my own employer crossed the line of disclosure.

Point taken. I thought of not linking to them, or even not mentioning them. But they do play an important part in the story of the post, and I don't think I'm helping them so much as I'm raising employees' and employers' awareness of their

Actually, my original implementation used Dijkstra's algorithm. But I think the linear table of suffixes (or prefixes if you prefer) is a cleaner approach.

Exactly. I prefer legal reform too, but something is better than nothing.

Glad to see positive feedback about the PATO proposal. I can't claim credit for originality -- but I was glad that, when I thought of it independently, I was quickly able to discover John Walker's proposal.

I am glad to finally see this story told in all of its gory detail. As a witness to this story, I was frustrated to see how Arlo and AJ never had a chance to win on the merits of their case, let alone on the merits of their technology. I ca

Would love to hear feedback on the "practical" part of my rant. Unfortunately most of the comments on the post focused on the merits of software patents. Let me be clear (as I am in the post): I don't like software patents. I think they sho

I'm obviously a big fan of LinkedIn, and I see them as a poster child for faceted search. I hope they take the next step and do interesting things with the skills data that is latent in their profiles. But I'm happy that they took the bold

Also, my friend is reading this page, and I hope he'll reach out to folks who have volunteered to help. Bad patents hurt everyone--you never know if you'll be the next victim. Regardless of your stance on software patents in general, I hope

I'm asserting that it's a bad software patent because I'm familiar with the details. You obviously don't have to take it on faith that my assertion is correct. Believe me, I'd love to share the details--and I will when my friend gives me th

Believe me, I'd love to give these guys bad press--TechCrunch or Gawker could do a nice story at their expense. But that's my friend's decision to make, not mine. The last thing I want to do is undermine his defense.
