```
#data: [{"amount"=>12.0},{"amount"=>25.50},{"amount"=>17.99}]
Segment.select("SUM((data ->> 'amount')::FLOAT) AS total_amount")
```

I have structure like project_data:jsonb field in postgres table
project_data: [{"data"=>"1", "template_field_id"=>1}, {"data"=>"10-11-2022", "template_field_id"=>2}, {"data"=>"Hi", "template_field_id"=>3}, {"data"=>"abc", "template_field_id"=>8}, {"data"=>"2", "template_field_id"=>9}]

data field will always have string values.
template_field_id will always have integer values (i.e. id of another table).

I want to get list of all records based on data field and template_field_id field. Below criteria only applies to data field values.

1. Filter by date range (i.e. between 2 dates)
2. Filter having exact text
3. Filter having number between range, including number (i.e. data field having number between 3 to 10)
4. Filter matching partial value.
5. How to group (Grouping Query)

Could you advise how to achieve this with single and multiple filters?
