How to search and filter for activities and links using “Regular Expressions”.

Use regular expressions to find nodes or edges with specific text in the “Label” or their “Data Property”. Here are some basic regex patterns

Wildcard (.):
- Matches any single character except newline.
- Example: “a.c” matches “abc”, “a1c”, “a@c”, etc.
Character classes [ ]:
- Match any single character within the brackets.
- Example: “[aeiou]” matches any vowel.
Negated character classes [^]:
- Match any character NOT in the brackets.
- Example: “[^0-9]” matches any non-digit character.
Quantifiers:
- “*”: 0 or more occurrences
- “+”: 1 or more occurrences
- “?”: 0 or 1 occurrence
- Example: “go*gle” matches “ggle”, “gogle”, “google”, “gooogle”, etc.
Anchors:
- “^”: Start of the string
- “$”: End of the string
- Example: “^dog” matches strings starting with “dog”.
Alternation ( | ):
- Acts as an OR operator.
- Example, if you want to select all 10 extracted longest paths then: “1|2|3|4|5|6|7|8|9|10″ matches either path”1” or “2”….”10″.
Grouping ( ):
- Groups characters together.
- Example: “(ab)+” matches “ab”, “abab”, “ababab”, etc.
Escaping special characters:
- Use “” before special characters to treat them as literals.
- Example: “*” matches an actual asterisk.
