feat: Add option to filter search results by url/pathname

[herbertnikolajewskidci]

• filterByPathName: false

  • This option allows restricting search context to the current URL.

• subPath: -1

  • This option only works if filterByPathName is set to true. It allows further filtering of the search context. Example: Suppose this is our endpoint: "/help/page1/subpage1/topic". If I set subPath: 2, then the search context will be limited to everything that can be found under help/page1/. Anything that's under /help/page3 or similar will be filtered out. subPath: 3 => then only help/page1/subpage1/ not help/page1/subpage2/*, etc. The default value is set to -1, which always allows searching the current page only as search context.
