Issue:
Bug: feat(globalsearch): Implement tag-based filters in global search



Add more explicit filters to global search:
Currently we rely on free form text search where opensearch matches the keywords across the entire document
We want to add a more refined & strict search query where we do exact matches on fields

filters to be added:
- payment method
- currency
- status
- customer_email

will need to add a filter_in_range function for the query builder as well to generate the corresponding query

## Description
<!-- Describe your changes in detail -->
Added more explicit filters to global search:
Currently we rely on free form text search where opensearch matches the keywords across the entire document


Filters added currently:

- payment method
- currency
- status
- customer_email

Can map multiple options for every filter for global search

## Motivation and Context
<!--
Why is this change required? What problem does it solve?
If it fixes an open issue, please link to the issue here.

If you don't have an issue, we'd recommend starting with one first so the PR
can focus on the implementation (unless it is an obvious bug or documentation fix
that will have little conversation).
-->
Adding a more refined & strict search query where we do exact matches on fields provides better results

## How did you test it?
<!--
Did you write an integration/unit/API test to verify the code changes?
Or did you test this change manually (provide relevant screenshots)?
