To find all chr3: To get all records with 22355591 you can run:
2grep -n -k3 inputfile chr3 grep ^22355591 input.txt
-n will split 'chr3' into 'chr' which is compared asciibetically and But if I<input.txt> is several TB big, it can be very slow. B<2grep>
uses binary search which only works if the file is sorted, but takes
less than 1 second to run:
2grep -H input.txt 22355591
You can also search for a shorter string to get all records starting
with 2235:
2grep -H input.txt 2235
Or you can search for multiple search strings:
2grep -H input.txt 12893827 22356142
=head2 Multiple keys
Input is sorted by SampleID, Chromosome, Position (in that order):
SampleID Chromosome Position Data
PatientA chr3 10002123 CCGTCTAATGGCTTGATTGGTACACCATGACATTGA
PatientA chr3 10003125 TCCATCGTCGGCGAGAAGGTACCAGGTAA
PatientA chr11 9999998 AATTCACAGTATGGCTGACGGTGTCGTAGCTACACG
PatientA chr11 10001240 TCCAGAAGTTTGA
PatientA chr11 10001260 ATAACGAGAACTTACGTTTTAAAAGGCCTA
PatientB chr3 10000125 GTCTTCACTTTATAAATGGATGATAGCCTTCA
SampleID is sorted as text. Chromosome is sorted by text first and
numerically for the number. Position is sorted by number.
To find all chr3 for PatientA:
2grep -H -k1,2N inputfile PatientA chr3
-N will split 'chr3' into 'chr' which is compared asciibetically and
'3' which is compared numerically. '3' which is compared numerically.
=head2 Not implemented To find all chr3 for PatientA and all chr3 for PatientB:
To find all lines with chr3,10000125: 2grep -H -k1,2N inputfile PatientA chr3 PatientB chr3
2grep -k3n,2n inputfile chr3 10000125
=head1 PERFORMANCE
Binary search requires seeks from the disk. But B<2search> is designed
so that multiple searches will reuse cached data. This means searches
will be faster the more you run.
You can improve the speed even more by sorting the input strings. This
will make it possible to reuse cached data more.
It can be even faster if you run multiple searches in parallel.
This is due to magnetic drives' elevator sorting of requests when
seeking and due to NVMe drives working faster with more queues in
parallel.

=head1 BUGS
B<2search> does not respect your locale setting. It assumes the input
is sorted with LC_ALL=C. If it is not B<2search> may give the wrong
result.
To solve this sort the input with B<LC_ALL=C sort ...>.
