How to convert binary data back to a float array in Elasticsearch/painless

由 只愿长相守 提交于 2019-12-11 17:16:39
问题 I am trying to efficiently store and retrieve an array of floats in elasticsearch 6.7. Numeroc doc values are sorted, which means I can't use them directly. At first I was using the source value of the field, but the performance on a large query is not great. I tried to encode the float array as binary and decode it inside my script. Unfortunately I'm stuck at converting a byte[4] array to a float in painless . In Java this would look like this Float.intBitsToFloat((vector_bytes[3] << 24) | (

How to sort results based on term position in elasticsearch >= 5.5?

由 删除回忆录丶 提交于 2019-12-10 21:55:05
问题 Since _index is no longer available in Painless scripting, hence solutions which used to work via accessing term-offset from _index in script_score do not work any more such as one advised here: Scoring by term position in ElasticSearch?. What's the preferred way to do this now? Thanks much for your help! 来源： https://stackoverflow.com/questions/49304331/how-to-sort-results-based-on-term-position-in-elasticsearch-5-5

ElasticSearch/Painless: How do I access/sum all values in an object

由 邮差的信 提交于 2019-12-06 15:14:52
I've been looking at aggregations, and at scripting using painless , and I am not able to figure out how to iterate/sum over all values in an object. Example: My mapping looks like "field1": { "properties": { "subfield1": { "type": "float" }, "subfield2": { "type": "float" }, "subfield3": { "type": "float" } } } Let's assume my data looks like this: { "field1" : { "subfield1": 50.0, "subfield2": 20.5, "subfield3": 30.5 } } I want to perform a range query on 50.0 + 20.5 + 30.5 , or, basically, access all the values within the field1 object in some way. Aggregations do not allow me to use wild

How can I do this in painless script Elasticsearch 5.3

由 こ雲淡風輕ζ 提交于 2019-12-06 12:00:28
问题 We're trying to replicate this ES plugin https://github.com/MLnick/elasticsearch-vector-scoring. The reason is AWS ES doesn't allow any custom plugin to be installed. The plugin is just doing dot product and cosine similarity so I'm guessing it should be really simple to replicate that in painless script. It looks like groovy scripting is deprecated in 5.0. Here's the source code of the plugin. /** * @param params index that a scored are placed in this parameter. Initialize them here. */

In Elasticsearch, how can I apply a timezone to a scripted date operation?
