Saved search is a comfortable solution, if you regularly search for objects with similar conditions. For example you can save a search filter, where you set, that the age of an ad is 1 day. The next day, only a few clicks will get you last days ads and you will not have to fill in the form again.
To save a search fill in either general or detailed search form, name the search filter and push Save search. After that you will find the filter under Saved searches alt.
You can use saved searches only if you have registered and logged in!
