Separating of Heading HTML tags

Hi,
First of all I want to thank for this project. This is very valuable.
As I noticed, while parsing the crawled html content, all heading tags ,including h1 to h6, are stored in the Elasticsearch as a single field (array) named headings. However separation of these tags ,as separate properties, can help searching and finding the best result because most of the times h1 tags have more important content than h6 tags and have more weight in the search score. It can be a useful enhancement in the stored entity in the Elasticsearch.
Thanks a lot.
