Hi, Just pushed a big feature to ES called Percolator. Percolator does the "reverse" of what ES does today. Instead of indexing docs and then running searches against them, one registers queries and percolates a doc among them, getting back which queries matched that doc. Tons of more features can be built on top of this core feature, would love to hear some feedback. Note, this feature is still experimental. Issue: [https://github.com/elasticsearch/elasticsearch/issues/issue/624](https://github.com/elasticsearch/elasticsearch/issues/issue/624) cheers, -shay.banon ---

Shay, Loving the pace of innovation! This looks really cool, exactly the type of idea Paul and I were thinking about when we asked about email alerts. Would this work for a query which spans multiple indexes? We're set to upgrade our production instances next week from 0.13 to 0.14.2 to take advantage of the substantial reduction in disk space needed for full text queries w/ highlighting. Thanks, David ---

> Would this work for a query which spans multiple indexes? It works a bit differently then the idea of searching across indices. You register a query under an index, and then you can percolate a doc against those queries. If you have several indices, you will need to register queries on each one.

Thanks. After thinking about it for a bit, I came to the same conclusion. David ---

Great! I can't agree more that this feature opens up a whole new world!

How would perculator play together with something like the twitter river? Thinking to make this really useful you'd want some kind of callback / webhook - [http://wiki.webhooks.org/](http://wiki.webhooks.org/) - to be fired when registered queries match. Or am I missing something? On Jan 13, 3:23 pm, Shay Banon [shay.ba...@elasticsearch.com](mailto:shay.ba...@elasticsearch.com) wrote: > Hi, > > Just pushed a big feature to ES called Percolator.

This feature is the core feature to get things going. Doing things like getting matched queries when indexing docs, and possibly publishing them is going to be built on top of it.
