Cannot look up a value of a custom property if the search considers uppercase letters

[PedroCozzati]

Affected module
Advanced Search - Custom properties

Describe the bug

When trying to search for assets based on a value of a custom property, if the search is done with uppercase letters, nothing is found, however, If you search the same value as LowerCase the advanced search works correctly

To Reproduce

1. Have a custom property with the value starting with an uppercase letter
   

2. Try searching for the asset by the value of the custom property using advanced search
   

3. The result should be this (Nothing found)
   

Expected behavior
It was supposed to have found the asset that has this value in the custom property "govDominio"

Version:

• OS: [e.g. iOS]
• Python version:
• OpenMetadata version: 1.3.2
• OpenMetadata Ingestion package version: [e.g. openmetadata-ingestion[docker]==XYZ]

Additional context
Searching everything lowercase works correctly, so the root of the problem may involve string manipulation

Other related issues

1. It also doesn't work very well if the value is made up of two words due to the space between them

2. The character "-" in place of the space also has the same result (not found)

It is probably not limited to just these cases
