Partially Addresses #962

(In general, OED likes to have at least one issue associated with each pull request. Replace [issue] with the OED GitHub issue number. In the preview you will see an issue description if you hover over that number. You can create one yourself before doing this pull request. This is where details are normally given on what is being addressed. Note you should not use the word "Fixes" if it does not completely address the issue since the issue would automatically be closed on merging the pull request. In that case use "Partly Addresses #[issue].)

Type of change

(Check the ones that apply by placing an "x" instead of the space in the [ ] so it becomes [x])

• Note merging this changes the database configuration.
• This change requires a documentation update

Checklist

(Note what you have done by placing an "x" instead of the space in the [ ] so it becomes [x]. It is hoped you do all of them.)

• I have followed the OED pull request ideas
• I have removed text in ( ) from the issue request
• You acknowledge that every person contributing to this work has signed the OED Contributing License Agreement and each author is listed in the Description section.

Limitations

@EthanV431 Thanks for your contribution to OED. I do not see that you have signed the CLA (see link in description) but it is checked. Can you please sign or let me know that the OED records are wrong. Also, did you do this work alone or with a team? If there are others then they also need to sign the CLA. It can be reviewed after the CLA is signed. I'm sorry for the delay in posting this.

Hello, I worked on this together with Tan Hyunh and Anvi. I signed my CLA, not sure about the others.

I see the CLA signed by @EthanV431 & @thuynh-9084. I do not see it for @anviik. Could Anvi sign the CLA or let me know if the OED records are off. Thanks.
