Support for nested field names

[lifeofzero]

Really great project! One thing I was curious about is supported nested field names. For example:

foo.bar
foo.baz
foo.zap

Our schema in Elasticsearch supports one-level nesting, and I was having hard time getting the following to work.

df.filter(df.foo.bar == 'jane').select('last_name', 'email','age').collect()

Any help or suggestions would be appreciated. If was searching directly against the ES REST API the filter looks like:

"query": {
"filtered": {
"query": {
"query_string": {
"query": "+foo.bar:jane",
"analyze_wildcard": true,
"lowercase_expanded_terms": false
}
}

I'm Sorry. The nested field is not on the roadmap currently. But It is a good idea if we could utilize the query_string of ES to implement such feature.

We might use script filter instead as a workaround.

Hi thanks for this cool library !
does this issue include nested queries as such :

{'query':{
          'nested': {
                    'path': 'docs',  'query': {
                                              'match': {
                                                      'docs.feature': 'search_term'
                                                       }
                                            }
                         }
            }
}
