How to search in blob binary wise, and how to export data binary wise

I've a table with a blob field for each row. The blob contains binary data, which can be represented as bytes or text ( using mysql workbench - open value in viewer)

1.Does anybody know how can I search specific sequence of bytes in a given bytes chunk(blob field), for example search for the sequence of bytes: 00 38 a7 in blob's binary representation

2.Is there any possibility to export all table values to csv with blob values in binary representation When I tried to export using mysql workbench I got for each blob ... as a value in csv.
