Many years ago, when I was building Lunr, it was initially based on IndexedDB, but it was _much_ slower and the datasets I had in mind easily fit in memory so I didn’t pursue it. N…

Using `charCodeAt()` for numeric keys is an interesting optimisation, I'm definitely going to try that out with Lunr.js. I'm also interested in _why_ that is quicker though, aren't…

Lunr.js [1] used to use a trie data structure and memory usage was a concern. The problem is that although the data structure compresses prefixes, it does nothing for suffixes. Dep…

The last time this article was on HN I took a look at adding Okapi BM25 to lunr, from what I remember the changes don't seem to huge, its just a matter of getting the time to sit d…

I'm fairly sure elastic lunr is a fork of lunr, I still seem to have the most commits even! [1] I'll have to take a look and see what @weixsong added, perhaps there are some change…

I've come across these two: * http://reyesr.github.io/fullproof/ * http://www.tipue.com/search/ Might be interesting to see how these also stack up.

Nice. It'd be interesting to see the comparative performance of the three libraries under test, e.g. time to results and possibly memory usage.

Who'd have thought the most English looking location would be in Wales ;)

Why is it a red flag for a browser-based javascript library to require a browser for testing?

That is almost exactly what lunr is doing. It tokenises the input text, stems the tokens and filters out any stop words. The index it can be searched, the order is not relevant, a …

Since the library can be run outside of the browser (using node.js for example) the index could be generated server side, and then just passed to the client. I hadn't considered th…

The example ( http://lunrjs.com/example/ ) indexes 100 stackoverflow questions, some of which are relatively long. If indexing performance starts to become an issue the whole searc…

I have a similar library here http://bit.ly/fTj2Ls that uses pushState to provide a routing layer so you can handle perform ajax (or anything else you want to do) when a link is cl…
