Bug: filter by language is not working.

[DivyanshuVortex]

The filter is not working as expected.
When selecting or searching for different languages, the results don’t change correctly —

• c++ shows 60,174 repositories
• cpp shows 2,405 repositories
• Any other language also shows 60,176 repositories (same as c++)

Here are 3 screenshots showing the issue:

• Page with “c++”

• Page with “cpp”

• Text typed in the web address

It looks like when the entered language doesn’t exactly match the options, the filter defaults to showing all Hacktoberfest repositories.
This might be happening because the filter option uses “c++” while the query uses “cpp”, causing a mismatch.

Please assign this issue to me — I’ll investigate and fix the problem.
