This ticket follows work done in #1226 to enhance ISBN and ISSN searches. After deployment to production, the ILL team has reported a few anomalies related to ISSN searches specifically, but this could also apply to ISBNs:
0048671X vs. 0048-671X
In this case, I suspect the inclusion of "X" may be breaking the pattern we expected. The ISSN specification does allow X in addition to numbers and hyphens.
NOTE: "X" is a valid character in the ISBN specification also.
