In this search, we'll look for observations that were taken in the Time-Tag mode, then limit results by filter.

Selecting an Operating Mode
The Hubble Space Telescope's instruments have many operating modes; we can use the 'Operating Mode' condition allows us to search for a particular mode. In this case, we want to filter for observations taken in the 'time-tagged' mode.
In the classic search form, 'Operating Mode' could be found as an option under 'User-specified' field. You could then enter your desired criteria in the blank box to the right.
Although the drop-down menu is still available, the new form also supports type-ahead. This allows you to type the name of the field, or a part of its description, and matching results will be returned.
Limiting Results to a Filter
In this search, we also choose to limit results that used filter G230L. For more filters, see the HST Filters/Gratings Page.
The 'Filters/Gratings' field provided a space to input your desired filters, although until the search was executed, you could not verify the validity of the filter.
In the new search form, the 'Filters/Gratings' field supports type-ahead; this makes it easier to find and enter a valid value.
