Search Database
  • Search form is constructed from searchable fields (as specified by site administrator)
  • Simple search: 1 textfield; searches items in all searchable fields with AND logic
  • Advanced search: textfields/radio buttons/single and multiple selects, for all searchable fields; searches items as follows:
    • Boolean AND or OR inside fields: for any given field with more than one term entered, use this boolean expression to combine terms
    • Boolean AND or OR between fields: for those fields filled out by the user, use this boolean expression to combine all these fields
    • Fields that have not been filled out in the form are not searched
    • For every field filled out, search the appropriate table for matches; for all matches, search the parent table to find related matches; do so recursively until arrived at root table
    • Using the boolean for between fields, combine hashtables to give the list of ids for all real matches
    • return those entries to the page
  • Search results are listed in the same way as "List items", see next
List items
