Hi all, I wonder if it is possible to use scripts within an index statement? Thanks, Adrian -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

In my scripts, I'd like to perform comparison on fields which are mapped as "date". Given the documentation, these types are json strings, but handled as Java long types internally. Using MVEL as scripting, I've found operators for value comparison. Can someone tell on which types (String vs. long) this comparison is performed?

Hi, I don't think you can use scripting while indexing. Scripting is more meant to on-the-fly generate content that you don't have when retrieving docs, for instance when searching, faceting etc. Regarding the type question, it depends on where you load the value from. Have a look here: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/modules/scripting/). If you load it from disk, using the \_source syntax, then it's going to be a string, like in the json. If you load it from the document fields (field data), it's going to be a long.

So, referencing the date field in an update (using ctx.\_source.) the comparison operators "\<,\>" should suffice.

Scripting is meant to be used during querying time. What are you looking to achieve? If you are looking at changing the content that is indexed, you can perhaps use a custom filter/tokenizer/analyzer or modify the data at the client (index) side.

I have a quite huge number of documents (\> 2 Bio.). When doing an overview of these using facets on a certain field, the querying time is just too long. So I tried to build a second index, holding this (aggregated) data. The scripting was intented to update th relvant fields for this index (such as first seen, last seen, etc.) Best regards, Adrian -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
