Splunk Search and Iterate over a log

Can I do the following in Splunk:

Search for a line using a query.

Iterate from that line onwards in the log.

search source=log.txt "search value"

log.txt Line 1 Line 2 Line 3 "search value" Line 4 Line 5

I would like my search to return Line 3.

I would then like to iterate the log in this order Line 3->Line 4->Line 5.

Is this allowed in Splunk and how do I do this?
