Hi,

1. I would like to use the attributes map in lucene FieldInfo to handle some custom properties. Is there any way to do it in Elasticsearch ?
2. Is there any plans to support bitmap as a datatype in ES/lucene so that one can make use of roaring bitmaps and can perform union, intersection operation over it ?

You can develop a custom plugin for that; there is no way to do that in the core elasticsearch.

You can file an issue [here](https://github.com/elastic/elasticsearch/issues) describing your use case, and depending also on other users' need, our development team will discuss if it something we would like to implement.
