Does the word "exgest" exist?

A colleague of mine found reference to the word "Exgest" in a contract. In context, this appeared to mean the opposite of the word "Ingest" which was used earlier in the contract. These words were intended to convey the consumption and processing of data in a system.

Does this word, "Exgest", actually exist, and what does it mean?

Edit:
List of prior research:
google: exgest
google: word definition exgest
google: site:dictionary.com exgest
reverse lookup: opposite of ingest
merriam webster search: exgest

Solution 1:

The proper antonym of ingest is egest not exgest. Etymologically e- serves the same purpose as ex-.

egest

To discharge or excrete from the body.

Solution 2:

There are also another two similar terms applicable for data flows:

ingress and egress

Solution 3:

I would suggest data import and data export.

Plain and simple and everyone immediately understands the meaning. (This advantage should not be underestimated, especially when non-native speakers are involved who also might not be familiar with latin.)
