Hi Jorg,

Sure. Thanks,

Just wondering what changed so much in 1.3? Is there sort of a quick fix? 
Or else, will just wait for an update from you.

Re: [ANN] Elasticsearch Simple Action Plugin

2014-06-07 Thread joergpra...@gmail.com

I have implemented a function score based conditional boost plugin for
demonstration.

Very useful for faking relevance scoring, in dependency of document field
values which were originally not meant to contribute for boosting.

A list of boost values can be specified in dependency of indexed values in
other fields in the document.

It may not fit exactly to your needs, but it should show the solution in
general - no reindexing, no scripting required. Instead, the plugin is
using the function score Java API.

I mean, you can add a MyOwnFunctionBuilder/MyOwnFunctionParser to
Elasticsearch via plugin. See
package org.elasticsearch.index.query.functionscore for the standard
implementations.

The functionscore code is masterpiece quality - no need to modify existing
code! It is pluggable.

A close example to what you want to achieve is
org.elasticsearch.index.query.functionscore.fieldvaluefactor

This would be an alternative to the AbstractSearchScript call
implementation path you have chosen so far

Re: [ANN] Elasticsearch Simple Action Plugin

2014-06-06 Thread Ivan Brusic

Function score code is perhaps the easiest to write for Elasticsearch. You
do not need to create a plugin for it, simply write the code with the
appropriate classes and deploy at as a jar to Elasticsearch's lib
directory. Done. That said, I still prefer to write native scripts as
plugins because they are logged as plugins on server startup. Far easier to
debug if something goes wrong.

Two tutorials:
http://www.spacevatican.org/2012/5/12/elasticsearch-native-scripts-for-dummies/
https://github.com/imotov/elasticsearch-native-script-example

Cheers,

Ivan

Great walkthrough :) ... I only miss the mentioning of the standard
language plugins for scripting (groovy, js, etc.) And rivers are not
obsolete, the "pull" method from a singleton "river" node is just
discouraged.

Re: [ANN] Elasticsearch Simple Action Plugin

2014-06-04 Thread joergpra...@gmail.com

As said, it is true that scoring scripts (like the function score scripts o
the AbstractSearchScript) need to reside on data nodes. Accessing fields is
a low level operation in a script so it is not possible to install such a
boost plugin that uses scripting on a data-less node. You would have to
install it on all the data nodes which might become tedious (but it is
doable).

Another issue is that you use scripting in a java plugin. I conclude from
this, the search should work later over the HTTP API by executing a
standard function score query with the boost script name (is that true?)

Writing a plugin, in a pure java environment, you have much more degrees of
freedom to supersede the script functionality and use other code paths. For
example, you could reuse the resource watch service from ES (used for
watching script file changes) to reload the boost info (which is in your
binary files I assume). Then you could build the query internally using the
Java API as a custom score query action and execute it from your favorite
(data-less) node (or from two nodes, for better fault tolerance / load
balancing).

Optionally, you could expose a new endpoint to the ES REST API, for example
"_search_with_boost", which works like "_search", but makes use of the
boost info files.

For a more generic solution, it would be convenient to convert the boost
info into a JSON parameter file so this could be loaded by the standard ES
settings/config routines and by other languages, also for better reuse by
others in the ES community :) An example plugin name could be "boost
control plugin"...

Absolutely, agreed.

The docs are sparse in my simple plugin too. I try to find some time to add
sample code for all the variants and explain the differences.

Re: [ANN] Elasticsearch Simple Action Plugin

2014-06-04 Thread virgil

Yeah, but I would consider the nondata node is already doing the job. --
"These "non data" nodes are still part of the cluster, and they redirect
operations exactly to the node that holds the relevant data. The other
benefit is the fact that for scatter / gather based operations (such as
search), these nodes will take part of the processing since they will start
the scatter process, and perform the actual gather processing." I just
uploaded my native script code in https://github.com/virgil0/TestPlugin. It
works with the function score query. You can see that there are 3 bin file I
need to load into memory. Thank you for reply.

Although I have built a few plugins during the years, they were river or

lot more digging, especially since there are very few to learn from. I
still would like to see a write-up regarding the different families of

Re: [ANN] Elasticsearch Simple Action Plugin

2014-06-04 Thread joergpra...@gmail.com

You need resources on all nodes that hold shards, you can not do it with
just one instance, because ES index is distributed. Rescoring would be very
expensive if you did it on an extra central instance with an extra
scatter/gather phase. It is also very expensive in scripting.

A better method is a similarity plugin like
https://github.com/tlrx/elasticsearch-custom-similarity-provider

Not sure how your code looks like though, maybe you can share it with the
community?

The problem is that only one copy of HashMap is needed to customize score of
all documents in the cluster. But as we have to install the plugin on all
nodes, the actual memory used is multiplied by the number of nodes in
cluster. I try to figure out one way to save the memory. Tried on non-data
node, but it seems not working.

Not sure if I understand your concern completely - as long as you're doing
things right in your code, it should be possible to allocate resources only
when required - this holds also for plugins.

Re: [ANN] Elasticsearch Simple Action Plugin

2014-06-03 Thread joergpra...@gmail.com

Usually, plugins that extend internal ES functionality should be installed
on all nodes. This is easy to remember and preferable from an
administrative view. All the nodes in the ES cluster must have access to
plugin code under all circumstances, especially when executing actions,
mappers, routers, discovery helpers, analyzer code, indexing helpers...

In this case, for the simple action demo plugin, you can install it just on
the node of the cluster where you want to execute the demo "match_all"
search from. The "match_all" search is then searching on all the indexes of
the cluster.

If you want to execute the demo plugin "match_all" search from other nodes,
you would have to install the plugin on those other nodes, too.
