Filtering

This part of the documentation deals with what can be done inside an existing collection to better organize it and find information.

Ordering list

| Top |

Collections are displayed in list according to a certain order. Default one is an alphabetical order for names. But this may be reversed by user.

When collections are displayed in Text or Image mode, user has to click on the list header that has a label corresponding to current collection type.

In Detailled mode, items may be ordered according to any of the values associated to them (but pictures) as long as it is displayed in the list. To use it, one just need to click on the column header. Clicking on it a second time will reverse the order.

Performing searches

| Top |

Inside toolbar or Filter menu, there is something named Find. It will open a window like this one:

Collection search

It lets user specify some searching criteria. Obviously, they will be different for each kind of collection (previous example was for movies collections). Once it has been validated, only collection members that match these criteria will be shown in list.

To show the whole collection (as before search was performed), there is the View all button in toolbar or corresponding button in Filter menu.

If nothing has been found, the list will be empty and instead of information, this will be displayed:

Nothing has been found

Advanced searches

| Top |

In the Filter menu, there is another item Advanced Search. It will open a window where all the searching criteria could be defined.

Window for Advanced Search

The type of search of search defines how the criteria should be handled. The first option corresponds to a logical AND where only items matching all of the defined conditions will be returned. The second one is for a logical OR and the items that matches one or more of the conditions will be returned.

The Add and Remove button lets the user add or remove some criteria. For each of them, a field should be selected, then a comparison and finally the value to use to perform the comparison.

Quick filtering

| Top |

Filter menu contains some simple and often used filtering features. They provide same behaviour as corresponding information into search window. But they are also here to make them quickly available. They can be combined together and also with search feature.

Once again, available filters will depend on the current collection. While most of them will have an immediate effect, some will require user to input a value.

Grouping items

| Top |

Collection members may be grouped according to a field selected by the user. This may be done quickly using the menu list in toolbar, or in a more accurate way with detailed mode settings. Indeed, to use this feature, it is mandatory to have the collection in detailed mode (setting the grouping field from toolbar will switch automatically to this mode).

Here is how it could like when grouping is activated. This example is a movie collection where movies are grouped according to their release date.

Groups of items

We call Master the item which allows the user to hide or show the others in a group. Master is generated automatically by GCstar and do not correspond to a real collection member. Its name will be the value of the field used to group.

Clicking on the master will display in the information area the ones corresponding to the first item in this group. But the information won’t be editable.

Mouse may be used to select which group an item should belong to. User has to click on it in the list and drag it onto a master (or somewhere in the list in this group) to make it part of this group. The item will be automatically updated to change the value of the grouping field.

Should you have a problem using GCstar, you can open a bug report or request some support on GCstar forums.
