Mrga means a forest animal, especially deer. These animals are so named because they constantly roam in search of food; matching the literal meaning of the word: "searcher."
Mrgaśīrṣā's symbol - a deer sniffing the ground - is essentially a literal depiction of the word Mṛgaśīrṣā ("Deer's face"). Soma is the deity of Mrgaśīrṣā. Soma is the god of a legendary elixir (also named Soma) that grants eternal youth and unsurpassed delight. Soma the "fountain of youth." This ties in nicely with the nature of Mrgaśīrṣā to inspire quests and searches. Literally, the word soma means "juice, sap, liquid."
