In case you haven't found this or any other solution yourself, perhaps you can find some information in the thread below. The question was phrased almost the same.

"Deleting everything (to end of line) after a certain string"
viewtopic.php?f=7&t=882

You may use something like the expressions below.
Be sure to have the multiline anchors option set correctly (I guess it should be unchecked).

Find:
(yourwordhere).*$

Replace by:
$1

$1 replaces the "yourwordhere" you entered between parentheses and does not so with .*$, which is anything that follows it. In effect, that part will be deleted.

This is another thread about something similar:

"Remove everything until certain word"
viewtopic.php?f=6&t=963

Slight change...

Assuming you are working with a file named 'test.txt'

The contents of that file would read:

Line 1
Line 2
Line 3
Delete After Me
Line 5
Line 6
Line 7

Point TextCrawler to the correct file location

Search: (Delete After Me).*$
Replace: $1

Case Sensitive: Up to you
Multi-line Anchors: Unchecked
Dot matches newline: Checked

This should replace 'Delete After Me' and everything that comes after it with 'Delete After Me'.

This should leave the file 'test.txt' reading

Line 1
Line 2
Line 3
Delete After Me
