This search allows the user to search by any column that exists in the main
extractions table for very specific searches not covered by the previous searches.
For example, to search for all newly added or reprocessed extractions on can
search on "proc_date" choose the "like" option then enter YYYY-MM-DD using the
current year and month. (Note: searhes use mysql pattern matching: "%" is a wildcard for one or
more characters; "_" is for any single character. E.g., try obsid
queries "like 14_1" or "like "14%1".)
