For text fields, we have implemented 'typeahead': in essence, an autocomplete feature which suggests the available values as you type. In the New HST Search, this is available for 'Dataset ID', 'Principal Investigator', and 'Names of Filters'. See the Figure 1 below for some examples.
Show API Query
Although using an API is often the most powerful and versatile way to search, programmatic access can be unintuitive for those who are new to it. Fortunately, the new search form includes a 'Show API Query' button, to the right of the 'Search' Button.
Clicking the button generates a query based on the current values in the search form. You can choose either a Python script that uses the astroquery.mast package, or a Curl script, as shown in Figure 2 below.
