Elasticsearch Implementation (In Progress)

Have worked out the problems with indexing and mapping. However, cannot get mult_field mapping working properly in the mapping. After changes to the mapping and the as_indexed_json method the index is not being populated at all. Console is not producing any errors. Store name with locality is the field that requires multi_field functionality.

Although basic mapping has been worked out the proper analyzers will still need to be applied for searching to be efficient.
