The summaries of the advertisements which matched your search criteria are displayed. The first time a search is run the matching advertisements are displayed in date submitted order, with the most recent first. To sort them select from the dropdown and click on go. If they are re-sorted then on subsequent runs of the search they will be automatically displayed in the new order. If there are too many matching advertisements to display on a single page the number of adverts displayed will be shown at the bottom of the page along with a "Next" button to go to the next page of advertisements. From subsequent pages there will be a "Previous" button to return to the preceding page and if necessary a "Next" button to go to yet another page of matching advertisements. If a large number of advertisements are returned by your search it may be preferable to refine the search and re-run it rather than trawl through hundreds of advertisements!
