Fair question. I'm running couchdb for a new project, and Lucene is the 'blessed' search backend for that.
However, (at least via couchdb) Lucene needs a whole JVM of its own, and I'm planning to run this on a VPS with pretty tight resources. A couple of MB in the same JVM as my site is a whole lot more appealing, and has the additional advantage of using native data-structures directly.
- jbooth 17y agoLucene's just a toolkit, it'll run in the same JVM that you're running clojure in, and while it can be memory-intensive if you're running a lot of searches over a big index, it's probably not any more memory intensive than what you're doing -- they've done a bunch of iterations already. Maybe you were thinking of Solr? That's the REST service that wraps Lucene but you can use the Lucene API from within your app just as easily if that fits your use case.
- mattdw 17y agocouchdb-lucene, which is what I was looking at, does require its own JVM. I didn't think to look at using Lucene directly. On the other hand, I'm quite happy with how this turned out, it's one less dependency, and it's been fun to write.
- jbooth 17y agoYeah, kudos for writing it, it's always good to write something like that and learn. If you find further needs, I'd really recommend looking at the "thin wrapper around lucene" approach, they've been banging on this problem for a decade and have a lot of lessons learned in their codebase.
