I think it would be highly useful to be able to use regex/wildcards in the search field. For example, I use tags to organize my observations. My tags look something like this (the underlying organizational system is not important to this example):
- Tag A: Expedition 50.4 - Microbes in Bird Bath A #2 pt3.7
- Tag B: Expedition 52.2 - Microbes in Bird Bath A #6 pt1.1
- Tag C: Expedition 52.6 - Microbes in Bird Bath A #2VI pt0.3
Currently, searching for ‘Microbes in Bird Bath A’ will find all of the above tags.
However, searching for ‘Microbes in Bird Bath A #2’ only finds Tag A, and cannot find Tag C. Currently it seems I cannot enter a search term that will give me both Tag A and Tag C together, even though they both contain the exact phrase “Microbes in Bird Bath A #2”.
Allowing regex/wildcards in the search would allow users with organizational systems to more easily find what they are looking for. The regex search to yield both Tag A and Tag C would be something like ‘Microbes in Bird Bath A #2.’ while the more typical internet search wildcard would look like 'Microbes in Bird Bath A #2’. Either method seems fine with me. Most users are probably more familiar with internet search wildcards than regex.
