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 |
|
nullsub()
The nullsub() function substitutes the variable with a default value if the variable specified by the first parameter is null:
| Service Manager function | Translated SQL equivalent: |
|---|---|
select ps.number, ps.title from probsummary ps where nullsub (ps.openen.by, “falcon”)=”falcon” |
select t01.”NUMBER”, t01.”TITLE” from PROBSUMMARYM1 t01 where COALESCE (t01.”OPENED_BY”, ‘falcon’) = ‘falcon’ |
The first parameter can only be a field name or an expression that can be evaluated beforehand, it cannot be an expression that cannot be evaluated before translation into SQL. The other parameters can only be constant numbers or expressions that can be evaluated to numbers before translation into SQL:
The following cases are valid:nullsub ( ps.category, “abc” ) //In this example, “category” is a field from file “probsummary”
nullsub ( $L.var, “abc” ) //In this example, $L.var is a local variable defined beforehand.The following cases are invalid:
nullsub ( ps.title + ps.brief, “abc” )
nullsub ( ps.title + $L.var, “abc” )
