Different criteria on search and advanced search bars:
•
the texts in all columns. The string mask can consist of several query strings.
The query string has the following properties:
• The ? wildcard replaces one character.
• The * wildcard replaces zero or more characters. If you have enabled automatic
refresh, you can reduce the number of variables (rows) displayed by entering more
characters in the query string between the two asterisks.
•
If you enter an asterisk (*) as the first and last character in the query string, the string
that meets the criteria can appear anywhere in the column. Otherwise, the string
must be at the beginning and/or end of the column.
• When limiting numeric data, characters can be used to limit numbers based on values.
These characters include:
• equals (=)
• bigger than (>)
• smaller than (>)
• bigger than or equal (>=)
• smaller than or equal (<=)
•
Vtrin does not add an asterisk at the end of the query string.
•
You can search for column texts that end in specific characters.
•
The query string is case-insensitive.
• The string mask can include several query strings that have to or cannot be included
in the displayed items. Use commas (,) to separate query strings. You can only use
exclusive query strings in the advanced search bar. If you use them on the search
bar, the string must be found in all columns to limit off a row .
• If you do not want the query string to be included in the search results, use an
exclamation mark (!) or minus sign (-) in front of it and add it to the string mask.
Exclusive query strings can also include asterisks.
•
The items selected are those that include one or all the "positive" search criteria
(the ones that do not begin with an exclamation mark or minus sign) and no
"negative" criteria (the ones that begin with an exclamation mark or minus
sign).
• For example, the string mask string1,string2,!string3,!string4 means that string1
and/or string2 must be included, while string3 and string4 cannot be included
in any of the displayed items.
• The following characters cannot be searched for - that is, you cannot use them
in the query string: "*", "?" and "," .The following characters can be used in a
query string but not as the first character: "!" and "-".
•
To avoid automatic refresh from causing too large of a load on the system, each
keystroke is followed by a short delay before the system initiates a search. This
allows you to enter the entire string mask before the search begins.
• Advanced Search Bar: Includes string, list, yes/no, or time span conditions related
to the column below. All the criteria in the selection boxes and the string criteria in
Search bar: Defines the string mask that is compared with
