This is a report on findings, nothing more.
I know that search in the collection and store both work without the /regex.
I can search using simple search strings, such as (all within my collection):
- e001 gives seven results
- f101 gives seven results
- a161 gives seven results
- e1011|f1012|a1674 gives three results
with /regex it works like this (all within my collection):
- /regex e0 gives no results
- /regex e0|f0 gives results only for f cards, but not e cards
- /regex |e0|e1 gives 1414 results for all e cards
- /regex |e0|f0 gives 1362 results for low e and f cards
In short:
without /regex the pipe character (|) is only needed between any two search items
with /regex the pipe character (|) is also needed before the first search item
Am I mistaken? I certainly see it this way, as the search results I found based on many separate searches
