Thank you for submitting your PR. The PR states are In progress (or Draft) -> Tech review -> Doc review -> Editorial review -> Merged. Before you submit your PR for doc review, make sure the content is technically accurate. If you need help finding a tech reviewer, tag a maintainer. When you're ready for doc review, tag the assignee of this PR. The doc reviewer may push edits to the PR directly or leave comments and editorial suggestions for you to address (let us know in a comment if you have a preference). The doc reviewer will arrange for an editorial review. |

@dhwanilpatel @bharath-techie @mgodwan We're trying to closing content gaps for the doc_value mapping parameter. Will one of you provide technical review of the content and example? Thank you. |

| OpenSearch indexes most fields by default for searching. While the inverted index allows quick term-to-document lookups, doc values enable efficient document-to-term access for sorting, aggregations, and scripting. |

Is this specific to keyword or any string related fields where doc values is supported ?
For numeric fields , this does not apply as inverted index / term lookups etc are not relevant.

Hi @bharath-techie: Will you please make any necessary changes for technical accuracy? This isn't a topic I'm familiar with so I need some guidance from the SME. Greatly appreciated. Please also see the editor's comment below.

"By default, OpenSearch indexes most fields so that they can be searched"? What inverted index (hasn't been mentioned)? Should "doc values" be "the doc_values parameter"? Should "access" be "lookups" (as in the first instance)?

@bowenlan-amzn Will you provide insight to the above questions? I have little to no guidance on the feature and need developer input. Thank you.
