[[Category:Actor]] [[born in::Boston]] [[height::180cm]]
Wildcards
[[born in::+]]
returns all pages that have any value for the property «born in».
Comparators
Placed after :: in property conditions.
- >> and <<: "greater than" and "less than"
- > and <: "greater than or equal" and "less than or equal" by default, but "greater than" and "less than" if $smwStrictComparators = true;
- ≥ and ≤: "greater than or equal" and "less than or equal"
- !: "not" ("unequal")
- ~: «like» comparison for strings
- !~: «not like» comparison for strings
Like, not like
In a like condition, one uses '*' wildcards to match any sequence of characters and '?' to match any single character. For example, one could ask [[Address::~*Park Place*]] to select addresses containing the string "Park Place", or [[Honorific::~M?.]] to select both "Mr." and "Ms.".
