Is your feature request related to a problem? Please describe.
In the v1beta1/assets api, we can filter based on query fields. Even though multiple query_fields can be supplied in the request, only one query value is taken.

For example -
with this API -

v1beta1/assets?types=table&q_fields=data.landscape.properties.entity,data.landscape.properties.attribute&q=mkns

It is possible to build a filter query like this ✅ -

WHERE type IN ('table') 
AND (data->'landscape'->'properties'->>'entity' ILIKE '%mkns%' 
OR data->'landscape'->'properties'->>'attribute' ILIKE '%mkns%')

But if we want to build a query like below, it is currently not possible. ❌

WHERE type IN ('table') 
AND (data->'landscape'->'properties'->>'entity'= '%abcd%' 
OR data->'landscape'->'properties'->>'entity' = '%mkns%')

Describe the solution you'd like
Make the Filter.Data field type to be map[string][]string, and in this block, handle it accordingly.

Describe alternatives you've considered
One of the alternative is to let the caller of this API, call it multiple times with different filters - but that would defeat the purpose of sorting, filtering and page-offsets in this API.
