Add Condition Overview
Panel |
---|
MAST Search offers many search parameters in addition to the commonly used Core Search Parameters. This enables more advanced searches for observations.
Add Condition Features and Functionality
To add additional search parameters, choose a column and then add a condition for that column. Each additional parameter should follow one of the three parameter-constraint syntaxes: String Fields, Numeric Fields, and DateTime Fields.
Note |
---|
The 'Target Descrip' column in the Add Condition feature has a data type of "substring", for which wildcard operators are automatically added at the beginning and end of the input string. For example, entering "jup" will search for all descriptions using"*jup*". Commas still work as with other data types, so entering "jup, white" will retrieve results with the condition "*jup*" or condition "*white*". |

After choosing a search column to constrain, type the condition to apply on the search parameter in the 'Condition' box. Add conditions according to its proper field constraints: String Field, Numeric Field, and DateTime Field. See the Core Search Parameters page for detailed descriptions of the constraint syntaxes and examples. |
