### Describe the solution you'd like:

> Search
https://keepassxc.org/docs/KeePassXC_GettingStarted#_search
> KeePassXC provides a robust search that enables you to find specific entries in the databases using different modifiers, **wild card characters, and logical operators**. By default, search considers the following fields when matching your query: Title, Username, URL, Tags, and Notes. To include other fields and/or narrow your search to specific fields, you can use the search syntax described below.

### Describe alternatives you've considered:

### Additional context:

_No response_

The issue names no KeePassDX files or tests. Start with the linked KeePassXC Search documentation, then locate KeePassDX's search entry point and determine how URL and domain matching currently works; done means wildcard queries such as *.example.com return the intended entries.
