Wildcard search #347

Closed tcouch closed 1 year ago

tcouch commented 2 years ago

Introduces the option to search with wildcards, as requested in #65.

How it works:

all punctuation except wildcard characters is removed from the search term
search term is broken down into a list of keywords
keywords are converted into regular expressions
regex lookup is carried out on all relevant content fields

Changes to behaviour:

terms do not match part of words if wildcards are not used; e.g. "ara" no longer matches "characteristic"
match exactly one character with a question mark; e.g. "ara?" matches "arat"
match zero or more characters with an asterisk; e.g. "*ara*" matches "ara", "arat", and "characteristic"
alternative wildcard characters can be set in settings
