I suggest you make a new custom record field which contains the data from "assgnmntNmbr" but strips out everything but digits (or other valid characters beyond hyphens). Then your query filter can just do an "includes" on the user-entered-text-similarly-stripped and reference that column (but you'll still display the original column and its value-with-hyphens).
If you are using Sync time evaluation, you can create a custom record field and use stripwith(rv!record[field],"-"), and then run the query on this field.
But AFIK you cannot achieve it if you are using real time evaluation as it has limited number of custom record function
