I want to able to search for multiple words on the same line.
For example, consider the file with the following contents:

....
11. 15 18 40 53 => 16 19 41 54
12. 03 15 27 64 => 04 15 28 65
13. 25 46 47 91 => 26 47 48 92
14. 10 15 32 53 => 11 16 33 54
15. 01 12 16 73 => 02 13 17 74
....

Say I want to search for occurrences of "15" or "53" or "92" on the same line. Then the correct lines that the search should identify are line 11 and 14. I don't want line 15 to be identified because the 15 is used as a numeral for the line, not as data. Also, I don't want the search to identify data to the right of the "=>" word, so the 15 on line 12 doesn't count either.

So what I want is a query for: find all occurrences of "15" or "53" or "92" that are found between "." and "=>". As a note, the numbers are increasing order, with no repetitions, on each line between the "." and "=>", so the search condition can be refined as: find the lines that have at least one of {15, 53, 92} between "." and "=>".

What I have so far is:

/[.].*\(15\).*\(53\).*\(92\).*\(=>\)

However, with this condition all three of "15", "53", "92" have to be on the same line.

Thanks.
