Using Special Operators in a Search

Special operators implement dedicated features and can be used to combine multiple search phrases.

Syntax:

\<search phrase>\<special operator>\<search phrase>

Or, depending on the special operator, simply:

Using special operators in a more complex search sentence can help you narrow the scope of the elements returned due to the keyword being used as a filter.

List of Special Operators​

| >Find all elements connected to the search result set.

EXAMPLE:Process1 \|>

Searches for all "Process1" matches and then searches for all elements connected to the result set.
>>Find all elements connected in output to the search result set.

EXAMPLE: Process1 >>

Searches for all "Process1" matches and then searches for all elements connected in output to the result set.
<<Find all elements connected in input to the search result set.

EXAMPLE: Process1 <<

Searches for all "Process1" matches and then searches for all elements connected in input to the result set.
Note

When searching for a Measurement type (Meter, Analyzer, etc..) the search engine will automatically look for elements connected to the element associated to the Measurement element.

Example: Measure element search
If searching for the measurement element (see next figure the red rounded meter), the search engine will look for everything connected to the flow "f_CRU_Feed".

EXAMPLE 1: Using a single "all connected elements" special operator

Let's say you want to detect conditions like this:

The resulting search sentence would be: Meter Test1 >=1 |> Test3 >= 1

The search engine would:

  • Look for all meters having Test1 >=1
  • Look for all connected elements having Test3 >=1

The result set would list:

  • All meters matching the Test1 >= 1 condition
  • All connected elements matching the Test3 >=1 condition
EXAMPLE 2: Using multiple "all connected elements" special operators

Now let's say you want to detect two conditions like this:

The resulting search sentence would be: Meter Test1 >=1 |> Test3 >= 1 OR (Test3 >=1 OR Test3 <=1)

The search engine would:

  • Look for all meters having Test1 >=1
  • Look for all connected elements having Test3 matching one of the two conditions

The result set would list:

  • All meters matching the Test1 >= 1 condition
  • All connected elements matching the Test3 >= 1 OR (Test3 >=1 OR Test3 <=1) conditions
