A. Introduction

The repository of the Jewish Community of Thessaloniki offers highly significant and remarkable content for both specialized academic audiences and the general public.

If you want to know what it contains, you can browse the content collections and the recommended content. If you have a specific question, you can use the Search function.

B. Navigation

To explore the content of the digital library, its organization is hierarchical. On the homepage, four main collections are displayed, two of which include sub-collections (listed in parentheses):

• Archives (Archive of the Jewish Community of Athens, Archive of the Jewish Community of Thessaloniki)
• Object Collection
• Printed Publications
• Special Collections (Deliyiorgis Archive from the Konstantini Collection, Konstantini Archive, Asher R. Moissis Collection, N. Benmayor Collection, O.P.A.I.E. Archive, Photographic Material)

Browsing the collections presents the digital items in a brochure-style layout. The order in which the items appear can be changed using the following options as sorting criteria:

• Most relevant (default), where the repository arranges content according to its own algorithmic criteria.
• Most recent, where the repository arranges content from the most recently created item to the oldest.
• Oldest, where the repository arranges content from the oldest created item to the most recent.
• Title A-Z, where the repository arranges content lexicographically by item title from smallest to largest.
• Title Z-A, where the repository arranges content lexicographically by item title from largest to smallest.

By default, the items are displayed in an icon grid. Each icon includes information such as time designation and title. If you prefer to view the items as a list for easier readability of titles, click the button.

At the top and bottom of the page, pagination for the items is displayed.

For collections with many items, the user can use the filters displayed on the left. When you select a value in a filter, the displayed items are limited. If you are using a computer, the filters appear on the left; for mobile devices, they appear by tapping the 'Filters' button. Furthermore, filters update to apply to the restricted items.

Once you find an item of interest, click its icon to view the metadata tab. From there, by selecting 'View in viewer,' you can see the digital record.

C. Search

With the search function, you can locate specific digital items that match certain words. You can use general search, which searches for words in all available information, or advanced search, which allows you to select specific parts of the available information, such as title or keywords.

1 General Search

Searches all fields of each digital item, and if at least one field 'matches'—that is, contains the words being searched for—then the item is included in the results. There are a number of aids to handle various issues.

1.1 Words

You can enter words without worrying about uppercase/lowercase letters or accents. Additionally, there are a number of tools described below.

1.1.1 Stemming

For each word we search for, the repository removes the ending using rules. This handles the variety of grammatical forms in Greek, which are particularly rich. For example, the search result is the same if you search for:

• president or presidents
• community or communities

1.1.2 Wildcard Characters

1.1.2.1 End-of-word match *

If stemming doesn't help, you can write the first few letters of a word followed by an asterisk. For example, 'diacheir*' will match words like 'diacheirizomai', 'diacheiristis', 'diacheirisi' (manage, manager, management).

1.1.2.2 Similar terms ~

If you're unsure about spelling, add ~ to the end of the word. For example, searching for 'epichírisi' (misspelled) returns no results, while using '~' like 'epichírisi~' will show relevant results.

1.2 Term Combination

1.2.1 Logical AND

By default, the terms are connected with a logical AND. Therefore, all terms must be present in the item for it to match the search. Example: Kliniki Pinchas.

1.2.2 Logical OR

Use OR between the terms, written in capital letters. Example: Kliniki OR Pinchas.

1.2.3 Logical NOT

Use either NOT in capital letters or a minus sign (-) directly before the word you want to exclude, with no space.

• Kliniki Pinchas
• Kliniki Pinchas -Aporoi
• Kliniki Pinchas NOT Aporoi

1.2.4 Changing Operator Priority

Operators have priority in this order:

• Logical NOT (highest priority)
• Logical AND (undetermined priority)
• Logical OR (undetermined priority)

Change priority using parentheses

• (Benmayor letter) OR (Benmayor letterhead)
• Benmayor (letter OR letterhead)

1.2.5 Phrase

To have the searched words appear next to each other in the document, enclose them in double quotes. Word order matters, so "Benmayor letterhead" differs from "Benmayor letter." Stemming is applied to the words in the phrase first.

2 Advanced Search

Add search criteria and perform a search. If you want to narrow the results, click 'Edit search' and add criteria. If the search is too narrow, remove some criteria. Each criterion has capabilities as described in paragraph 2.
