Regression in Search: Literal Search Misses Matches That Regex Finds

[niontchev-endurosat]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.106.3
• OS Version: Windows 11 Enterprise/26100.7171

Steps to Reproduce:

1. Open a C/C++ project with these lines:
   //#define HAVE_VERBOSE_MESSAGES /* Recommended during development prints errors and warnings */#if defined(HAVE_VERBOSE_MESSAGES)Show more lines
2. Search for HAVE_VERBOSE_MESSAGES with regex disabled.
3. Enable regex and search again.
4. Compare results.

Comments:
The new search implementation in VS Code appears to have a regression. When searching for a simple string like HAVE_VERBOSE_MESSAGES when Regular Expression enabled/disabled:

1. Regex disabled (literal search): Finds only one match in the header where it is defined:
   /#define HAVE_VERBOSE_MESSAGES /* Recommended during development prints errors and warnings */
2. Regex enabled: Finds two matches (both correct) in the definition header and in another file:
   -- first match
   /#define HAVE_VERBOSE_MESSAGES /* Recommended during development prints errors and warnings */
   -- SECOND MATCH
   #if defined(HAVE_VERBOSE_MESSAGES)
