Find and Search for Entities

The search bar can be used to find and filter entities in a browser.

Note: The following covers searching in HyperMesh browsers. The search syntax is HyperView and HyperGraph browsers varies slightly. For more information, see the Results Data or Plot Data chapters.

Perform a Quick Search

  1. Enter the Name or ID directly in the browser search bar.
    Figure 1.


    Entering this queryReturns this result
    shell All entities that contain shell in their name.
    "shell" All entities with the name shell.
    shell* All entities starting with the name shell.
    *shell All entities ending with the name shell.
    *shell* All entities that contain shell in their name.
    2 or "2" All entities with the ID 2.
    1-4 All entities with the IDs in range 1 to 4.
    1,5,9 All entities with the IDs 1, 5 and 9.
    ID=2* All entities with IDs that start with the number 2.
    ID=*2 All entities with IDs that end with the number 2.
  2. Press Enter or click to execute the search.
  3. Clear the search and return to the default browser view in the following ways:
    • Delete the search and press Enter.
    • Click x.
    • With the cursor's focus on the search bar, press Esc.
Tip: When the entry is alpha or alpha-numeric, the searched is performed on the names of entities. When the entry is only numeric, the searched is performed on the IDs of entities.

Perform an Advanced Search Using Auto-completion

Interactively build search strings using a dynamic suggestion list.

  1. Access the list by clicking the text field of a browser search bar.
    Figure 2.


  2. Select attributes, operators, and values to append the correct syntax to the search string.
    The search syntax follows this basic form: <attribute> <operator> <value>.
    Figure 3.


    Note: The attributes available in the list are the same as the current active browser attributes (columns). If you do not see an expected attribute, make sure the corresponding browser column is turned on.
    Entering this queryReturns this result
    Name~Bpillar Entities that contain Bpillar in their name
    Name!~Bpillar Entities that do not contain Bpillar in their name
    ID~5 Entities with an ID that contains the number 5.
    ID!~5 Entities with an ID that does not contain the number 5.
    Name=Bpillar Entities with the name Bpillar
    ID=10 Entities with an ID equal to 10
    ID!=10 Entities with an ID not equal to 10
    ID IN(5,10,15) Entities with an ID equal to 5 or 10 or 15
    ID NOT IN(5,10,15) Entities with an ID not equal to 5 or 10 or 15
    ID=100-250 Entities with an ID in the range of 100-250
    ID!=100-250 Entities with an ID not in the range of 100-250
    ID=8*3 Entities with IDs starting with 8 and ending with 3
    ID=[0-9][0-9][0-9][0-9][0-9]6 Entities with IDs ending with 6 in 6-digit numbers
    ID=[0-9][0-9][0-9][0-9]2[0-9][0-9][0-9] Entities with IDs with 2 at the 5th position in 8-digit numbers
    Entity=Properties AND ID>10 Properties with an ID greater than 10.
    Entity=Properties OR ID>10 All properties and other entities with an ID greater than 10.
    ID>=10 AND ID=<20 AND Name~Bpillar Entities that contain Bpillar in their name and have an ID greater than or equal to 10 and less than or equal to 20.
    Include=1 AND Material E=210000 OR Material E=220000 Materials with E=210000 under Include1 and Materials with E=220000 under all other includes.
    Include=1 AND (Material E=210000 OR Material E=220000) Materials with E=210000 and E=220000 under Include1.
    Include=1 AND Material E IN(210000,220000) Materials with E=210000 and E=220000 under Include1.
    Include=1 AND Property T NOT IN(1.5,3.5) Properties with Thickness not equal to 1.5 or 3.5 under Include1
  3. Press Enter or click to execute the search.
  4. Clear the search and return to the default browser view in the following ways:
    • Delete the search and press Enter.
    • Click x.
    • With the cursor's focus on the search bar, press Esc.
Tip:
  • Press the Down Arrow key to scroll thought the list of attributes, operators, or values.
  • Press Tab or Enter to select the attributes, operators, or values
  • Press Esc to dismiss the list of attributes, operators, or values.
  • While searching for text with space or special characters, use quotes (“ ”).
  • To search multiple values with a single attribute entry, use a coma after the first value selection without a space.
  • Double-click on an attributes, operators, or values to invoke suggestion list.

Use Column Filters to Build a Search

Use column filters to quickly search any attribute that is added to a browser as a column.

  1. Hover over a column name then click the filter icon .
  2. Type a value or select from the suggestion list then press Enter or click .
    The value entered is converted to the correct syntax and shown in the search bar.
    Figure 4.


    You can also use operators in the column filter to refine the search.
    Figure 5.


    A column filter icon indicates the column on which the filter is applied.
    Figure 6.


    Multiple column filters can be applied. The search string is appended in the search bar.
    Figure 7.


  3. Clear the search and return to the default browser view in the following ways:
    • Delete the search and press Enter.
    • Click x.
    • With the cursor's focus on the search bar, press Esc.

Use Predefined Filters to Build a Search

Use predefined filters to quickly filter the browser contents with selected or displayed entities

Predefined filters are supported in Model Browser entity views, the Part Browser, and the Subsystem Browser.

  1. Access the list of predefined filters by clicking the drop-down button next to the search icon.
    Figure 8.


    • Selected - Filters the browser with just the selected items. The Selected filter works for selection in both the browser and the graphics and should be reapplied after appending an existing selection.
    • Displayed - Filters the browser with entities that are displayed in the graphics. When the Displayed filter is applied in a browser, the filtered results are automatically updated upon changing the display state of the selected entities.
    • Current - Filters out the current collector.
  2. Clear the search and return to the default browser view in the following ways:
    • Delete the search and press Enter.
    • Click x.
    • With the cursor's focus on the search bar, press Esc.
Tip: After applying predefined filters, the search string can be further appended with more arguments to refine the search results.

Access Recent Search Strings

Click the text field of a browser search bar.
Your recent searches are indicated by the icon.
Figure 9.


Clicking on a recent search string auto-applies the filter and shows the search string in the search bar.

Clicking Remove removes the selected search string from recent history.
Note: A maximum of 5 recent searches are shown. Remove the latest strings to see previous search strings.
