BUG: Explorer Plugin (Everything): time-intensive queries won't cancel

### Checks

- [X] I have checked that this issue has not already been reported.

### Problem Description

Emptying/Closing the search during a time-intensive query (f.e. using the [function](https://www.voidtools.com/support/everything/searching) width:>100) doesn't seem to stop it (loading indicator still running), leading to no results from this plugin - others still deliver - in later queries until Flow Launcher is restarted or the initial query finished. De-/activating the plugin doesn't help.

The Everything software itself immediately shows results as they are found, not only after the query is finished. That would be a useful addition, should the SDK support it.

### To Reproduce

1. Enable Everything in the Explorer plugin
2. Have a bunch of files on your system
3. Type a function into search, e.g. width:>100
4. Input another file-related query or clear the input
5. Expect no result from Everything
