Different operators are available for each attribute. Some examples:
Filter rule |
Explanation |
Project name = Station |
Finds attributes exactly matching this string: Station Uppercase and lowercase letters are taken into account. |
Project name like station |
Finds attributes exactly matching this string: station Uppercase and lowercase letters are ignored. |
Project name = *station |
Finds attributes that end with the term "station" (south_station, central_station) Uppercase and lowercase letters are always ignored if the string contains an asterisk (*). |
Project name = *station* |
Finds attributes that contain the term "station" (south_station_platform, central_station_terminal) |
Project name <> ... |
Identical to "="; the only difference is that only attributes whose occurrence is not equal are displayed. |
Project name > P |
Finds attributes whose occurrence comes after the capital letter P in the alphabet: for example, all projects from R on such as Riga, Southern Wales. |
Project name >= R AND project name < S |
Finds attributes that start with the capital letter R. |
Many custom project attributes contain numerical values. The system checks whether the value entered is a numerical expression and if so, it applies numerical criteria. Example: Numerical construction volume >= 1000 finds 1000.0 but 1ABC is not found.
Filter rule |
Explanation |
Construction volume >= 1000 |
Numerical query; all numerical occurrences whose integers are greater than or equal to 1000. |
Construction volume >= 1000.5 |
Numerical query; all numerical occurrences whose floating point numbers are greater than or equal to 1000.5. |
Applies to the "=" and "<>" operators accordingly. |
|
Construction volume like 1000 |
"like" is always used alphabetically; never numerically. This condition finds attributes that match the string 1000. |
|
|
Description = "1000" |
You can force the system to look for a numerical value alphabetically by enclosing the string in brackets ("). This condition finds attributes whose occurrence is exactly 1000 (and not 1000.0). |
Note: If an attribute does not exist, it cannot be found. This also applies to the "<>" operator: description <> museum, for example, only finds projects containing the description attribute that is not equal to museum.
