Searching your way through vim

Matching a word "exactly"

/\<hello world\>/
\< and \> mark the start and end of a whole word resp.

Searching between 2 words (inclusive)

This will highlight everything b/w "red" and "blue" on the same line.
\& also called as "Branch" matches the last pattern but only if all the preceding patterns match at the same position
Example: Find f-strings f"\&.*"

Search between 2 words on different lines.

This will highlight everything between hello world.
Example: Find try/catch block hello\_.*world
"\_.*except" matches all text from the current position to the last occurrence of "except" in the file.
Read :help pattern.txt for everything related to pattern searching.
