The aim of the development of PicApport is to find photos without too much effort. As an introduction we would like to briefly explain the possibilities of the full text search in PicApport.
Of course PicApport can do much more. See also the links at the end of this page.
PicApport distinguishes between four types of information (metadata) that are stored in a photo (see the example image below):
Once the PicApport Server has been configured, it searches regularly for new images in the predefined directories.
For each new found photo PicApport tries to extract as many "words" as possible from the existing metadata and offer them for search.
Special characters or words with less than 3 letters etc. are eliminated. The following picture should show this process by means of a vacation photo.

Definition (Source: Wikipedia) A synonym is a word or phrase that means exactly or nearly the same as another lexeme (word or phrase) in the same language.....
Often the photos of the own photo collection come from different sources. The pictures were then often already provided with metadata.
A typical example would be pictures you get from friends or relatives. E.g. you may use the word journey for vacation journeys of but you son uses the word vacation. A search for journey will not find then the pictures made by the son which have been tagged with vacation.
Other typical use cases for synonym dictionaries are:
How to create a synonym dictionary is described in The directory structure of the PicApport Server (under the entry picapport/thesaurus) including a well documented example file.
Definition (Source: Wikipedia) A phonetic algorithm is an algorithm for indexing of words by their pronunciation. Most phonetic algorithms were developed for use with the English language consequently, applying the rules to words in other languages might not give a meaningful result.
Since version 7.5 PicApport supports phonetic search (Double Metaphone is default on English servers) with the ~~Operator (double tilde operator).
Example: Input ~~Salvador should find Salvador, Salvadore, Salvadori, Salvati, Salvatore
Under Fuzzy-Search we summarize in the documentation the use and configuration of the phonetic search, the synonym dictionary and the tilde(~) operators.
In connection with the phonetic search, the thesaurus and the Tilde(~) operators, PicApport offers several configuration options. For example, it can be defined whether each search query should be automatically searched in the thesaurus and/or via the phonetic search or not.

Modern cameras and mobile phones make it possible to add a geo-tag to photos as soon as they are taken. It is also possible to create geo-tags for photos afterwards, e.g. with PicApport.
If photos are provided with a geo-tag, these can be queried very easily via the integrated map module of PicApport.

If one has found photos over the full text search, these are often thematically not coherent. Using the relative search, a new query can now be started from a certain photo (thumbnail):
Photos from the same day
Photos from the same month
Photos from the same year
Photos within the same hour
Photos in the same directory
Photos nearby (if GPS information is available)
Photos with the same tags (selectable)
The following screenshot shows how it works:
Typically, photos are stored on the server in a hierarchical directory structure. Related photos are stored in a directory.
The directory browser can be accessed directly from the PicApport start page (landing page) via "Folders" and allows navigation through the directory structure configured for the PicApport server.
The Timeline (since version 8.1) displays all directories in their temporal context, regardless of their position in the directory tree. Decisive for
the position (chronological order) of a directory in the Timeline is the oldest photo in the directory. The timeline is always sorted in descending order and thus allows access to current photos with only 2 clicks. It shows the name of the directory and the title of the first photo found. If the title is in ( ) there are photos with different titles in the directory.
The built-in filter function within the timeline allows full text filtering on directory names and titles. You can also filter by year by entering a four-digit number. The following screenshot shows the individual elements and possibilities of the opened Timeline.
Die Timeline can be controlled with User Options. The timeline is also controled by a user permission: "Permission to use the Timeline. (Visibility: Timeline)" (see: PicApport - Usermanagement)
Of course you can also try out the timeline in the online demo: https://en.onlinedemo.picapport.de
