Allow blanks as a filter criteria in the find in files dialogue

Description of the Issue

While currently blanks are being used as a seperator for multiple filter criteria the "Find in Files" filter field, it's not possible to explicitly use blanks as a filter criteria for file names. Using blanks as a filter criteria should be possible if either the filter was defined as a multi-string input field (like e.g. Multi_SZ registry values in Windows can be edited) - OR - the use of double colons was allowed to mask filename filters containing blanks (while double colons " aren't allowed as file / directory name characters in Windows / UNIX file systems and using those to mask file names is common practice)

The original issue was described in the Notepad++ community forum already:
https://community.notepad-plus-plus.org/topic/22487/bug-in-find-in-files-filter-of-notepad-8-2-1-x64/7

Steps to Reproduce the Issue

Have a directory containing files with blanks in the filename. In my example there were
SAP 7.60*.XML

• and -
  SAP 7.70*.XML
  files contained in the search directory folder "C:\UEMConfig\T\general\FlexRepository\Shortcut".

When I used
SAP 7.70*.xml
as a "Find in Files" filter, I had 0 hits:

The search results in 0 files found…
Search “7.60” (0 hits in 0 files of 0 searched)

When I instead then search for SAP*.xml it properly finds files:
Search “7.60” (13 hits in 12 files of 13 searched)
but in this case unfortunately the hits also contains results from SAP 7.60*.xml (which should not be part of the replacement result set, it was only used to show that the files exist).
C:\UEMConfig\T\general\FlexRepository\Shortcut\SAP 7.60 Netweaver - SAPLogon.xml (1 hit)
C:\UEMConfig\T\general\FlexRepository\Shortcut\SAP 7.70 Netweaver - Analysis for Microsoft Excel.xml (1 hit)

What I originally wanted to do is replace 7.60 by 7.70 in all SAP 7.70*.xml files, which is impossible with the current Notepad++ version's filter

Also using "SAP 7.70*.XML" returned no hits.

The official workaround to use SAP?7.70*.XML is not exactly matching, while this would also allow replacement in SAP-7.70*.xml files (if those existed). ? is a single character wildcard, therefore not one-to-one (unique).

Expected Behavior

allow explicit searching for files containing blanks in the file name in the "find in files" filter dialogue

Actual Behavior

the filter uses blanks as a separator for multiple search criteria
SAP 7.70*.xml
is interpreted as a search for
SAP
-and-
7.70*.XML
files,
"SAP 7.70*.xml"
is interpreted wrongly.

Start at the Find in Files filter dialogue and review the linked community-forum report for the existing space-separated parsing behavior. Compare the SAP 7.70*.xml examples with the quoted and wildcard forms; done means a filter can explicitly match filenames containing spaces without also matching unrelated filenames.
