Search Guide
In this guide we show you the basic features of Arcanum's search engine used on Arcanum Newspapers. This is a high-performance complex search system we have been developing the last few decades.
Use the features listed here to make complex search terms by typing the search fields into the search box.
Search fields
TEXT |
Full text | In this case the search system does not distinguish between accented figures and finds the inflected forms of the expression (default) |
TEXT_EXACT |
Full text (precise) | Shows only the pages with exactly the same form of words |
DATE |
Date | Filter the results according to years. In daily newspapers you can also narrow down the time for a given day. Format: yyyy-mm-dd |
The default search field is TEXT. If you do not use any other search fields the given word may appear in accented form or inflected.

Examples
Results include all the words you typed:
petőfi OR kossuth(link)petőfi OR jókai(link)petőfi OR jókai OR kossuth(link)petőfi OR kossuth OR jókai OR arany(link)
Search for expressions
Using the quotation mark you will get results where the words are next to each other. The same functionality can be accessed by using the 0W operator. The two examples below show the same results:
Exact terms
If you want to get the most exact match, you need to search in the exact search field (TEXT_EXACT) and use the 0W operator or the quotation mark:
Results containing the keywords at a certain distance
Csokonai 1W Mihály(link)magyar 3W múzeum(link) Results like: Magyar Nemzeti Múzeum, Magyar Természettudományi Múzeum… etc.
This gives you the opportunity to search for pages that have specific words close to each other. The example below shows the result of a 10 words distance search:
Petőfi 10W Kossuth 10W Arany 10W Jókai(link)
In optional sequence:
Petőfi 10N Kossuth 10N Arany 10N Jókai(link)
Excluding words
You may want to filter out some false results. In this case you can use the NOT and WNOT operators.
bor WNOT TEXT_EXACT=(bőr*)(link)
Narrowing the date interval
The following example on Sándor Petőfi lists the references before the Revolution in 1848:
"Petőfi Sándor" AND DATE=(1840--1847)(link)
You may also search for specific days. It is important to know, that this option only gives accurate results for journals that appear on a daily basis.
"Petőfi Sándor" AND DATE=(1840-05-13--1843-04-17)(link)
Search for authors
AUTHOR=("Kovács László")(link) Search for articles by Kovács László.AUTHOR=("Kovács László" OR "K. L.")(link) Search for articles by Kovács László or K. L.
Search in captions
CAPTION=(Puskás)(link) Search for pages where Puskás appears within an image's caption.
Complex examples
You can search for those documents that appeared between 1845 and 1846, include Sándor Petőfi, but do not contain Lajos Kossuth:
"Petőfi Sándor" AND DATE=(1845--1846) NOT "Kossuth Lajos"(link)
Or try the same using truncation characters. Here you can filter out possible misspellings or errors of the optical character recognizer.
Pet!fi* 0W Sándor* AND DATE=(1845--1846) NOT (Kossuth 0W Lajos*)(link)
Search for documents published between 1930 and 1990 which contain Petőfi Sándor in an image's caption and Szabó Ferenc as the author.
CAPTION=(Petőfi Sándor) AUTHOR=(Szabó Ferenc) DATE=(1930--1990)(link)
Search for documents published between 1930 and 1990 which contain Petőfi Sándor in an image's caption, Szabó Ferenc as the author and they belong to the same article.
CAPTION=(Petőfi Sándor) S AUTHOR=(Simon Ferenc) DATE=(1930--1990)(link)
