Today I found a useful reddit thread:
d/<word> and it will delete until that word.
A truly mindblowing thing is the concept of search-offset (
:h search-offset). By specifying modifiers like
+, - etc at the end of the search command you can specify how much of the match is to be included. For example
c/word/echanges till the end of word. Similarly
d/word/s+2deletes till r of word. The modifiers +, - can specified to indicate number of lines to offset.
