Support for extended substructure searching in BINGO Elastic

I've followed the template that was provided for raising issues, but I was more just hoping to understand if there are any plans for extending the features of BINGO Elastic and if so, if there's any approximate timelines for the work.

Thanks for all the work you have done in providing Indigo/BINGO.

**Background**
The relational database backed BINGO packages support substructure searching with query atoms, atom lists, constraints on valence, hydrogen substitution, query bonds and a number of other options. Additionally, there are options to search with SMARTS. Are there any plans to provide some or all of this functionality in the Elastic/Open Search backed BINGO package?

**Solution**
An ability to use options that allow more control over the query objects that are used to define the substructure query. Whether that be through support of more special structural atom/bond descriptors or SMARTS. So that the searching experience is on a par with the functionality available in the Relational backed versions of BINGO.
