Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Words and Phrases
| Search for | Example | Results |
|---|---|---|
| A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
|
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Using Boolean Operators
| Search for | Operator | Example |
|---|---|---|
|
Two or more words in the same topic |
|
|
| Either word in a topic |
|
|
| Topics that do not contain a specific word or phrase |
|
|
| Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
| A combination of search types | ( ) parentheses |
|
RAD functions: parse() and evaluate()
Returns the value of a given expression.
Syntax
evaluate(parse(exp, 10 )
Note The data is the character string to parse and the parse type is the numeric value normally passed into the parse function.
Example
If there is an expression $lo.username="Sys.Admin" in the useroptions table, this example returns the value of that expression.
if (evaluate(parse(expression in $l.file, 10)))
$userIs.Sys.Admin = true
Note The expression works when the statement being evaluated and parsed contains thread or global variables. It does not work for local variables. However, you can transfer local variables to thread variables before calling the parse and evaluate expressions.
