Hey @ionos_help_uk - why are you charging long-term customers like me more than double that of new customers for the same server and terms? This kind of “loyalty penalty” is banned now in some industries. Is charging the same rate too much to ask?
Significant term identification. Clustering. Pure JavaScript working with a simple json file of news headlines.
Honoured to join the lineup of search experts interviewed in this series. We talk myths, “OR is mORe,” and how vectors should be treated like plasticine, not porcelain. Thanks Itamar and Zevi! pulse.support/top-voices/mar…

I wanted to share what I learned from Tantivy's "Search Benchmark, the Game", so I set up GitHub pages and wrote two blogs, on general observations on the benchmark jpountz.github.io/2025/05/12/ana… and how it helped drive performance improvements in Lucene jpountz.github.io/2025/04/12/why…
A genuine work email I received one time: “Company policy requires you to undertake security training. To take the course visit [site I’d never heard of] and install the browser plugin.” I replied “No. Did I pass?”

Example of the Boolean query’s detailed match profile - useful for human or AI refinement.
