Update search parser to search within codeblocks

[coszio]

Search parser right now works great as long as what you're looking for isn't inside a codeblock. This is specially notorious when searching info that lives in the Configuration page.

If it doesn't make sense to add semantic search to code-blocks, then using full-text matching/search might still be useful

Quick repro example:

• look for default_segment_number in the search bar, nothing useful will appear
