Re: ANN search current state

would it make sense to create a separate Lucene module for ANN search ? we could then experiment with the different approaches and compare them across the same benchmarks. On Thu, 16 Jul 2020 at 23:14, Ali Akhtar wrote: > I’m a bit of a layman in this area, but if we are talking about formats

Re: Optimizing a boolean query for 100s of term clauses

hi Alex, I had worked on a similar problem directly on Lucene (within Anserini toolkit) using LSH fingerprints of tokenized feature vector values. You can find code at [1] and some information on the Anserini documentation page [2] and in a short preprint [3]. As a side note my current thinking

Re: Possible to cause documents to be contiguous after forceMerge?

improved locality of "near" documents could be used to avoid loading some segments during the retrieval phase for certain use cases (e.g. spatial search). Il giorno mer 16 nov 2016 alle ore 09:45 Ishan Chattopadhyaya < ichattopadhy...@gmail.com> ha scritto:

Re: POS tagging in Lucene
