Full-text search¶
The full-text search searches all relevant fields of the archival records at once: titles, reference codes, text fields, linked actors, places and keywords — and also the text recognised by OCR from PDFs and images.
What is searched¶
For each archival object, the following are combined for the search:
- Titles of the object and of all superordinate units (fonds → series → file → document)
- Reference codes (current and former) as well as the internal ID
- Designations of the level of description, the object type and the location
- Datings
- Linked keywords in all available language variants
- Linked places
- Linked actors (only those publicly visible)
- Text fields that are visible in the external form
- OCR text from media (PDFs, images)
Extended view for internal editors
For logged-in users from the user_intern role upwards, the following are searched in addition:
- private actors
- all text fields (including those visible internally only)
- objects marked as private
Search behaviour¶
Word beginnings are recognised automatically¶
Wildcards (*) are not necessary — the search automatically finds all words that begin with the search term entered.
| Search | Finds |
|---|---|
alkohol |
«Alkohol», «Alkoholverbot», «alkoholisch» |
müller |
«Müller», «Müller-Weber», «Müllers» |
But not in the middle of a word
kohol does not find «Alkohol». The search only takes effect at the beginning of a word.
Several words are combined with AND¶
| Search | Finds |
|---|---|
alkohol verbot |
Records in which both terms occur — they may be any distance apart |
Quotation marks for exact phrases¶
| Search | Finds |
|---|---|
"rudolf leder" |
Only records in which this sequence of words occurs exactly like this |
#rudolf leder# |
Identical — # is an alternative notation for " |
With a phrase, word beginnings are not searched automatically — the phrase has to occur exactly.
Very short words are ignored in phrases too
Words of fewer than 3 characters and some English stop words (the, for, and) drop out of the comparison even within quotation marks. A phrase such as "AG Reinach" therefore effectively matches only «Reinach».
Terms with a hyphen¶
Terms with a hyphen (e.g. Arp-Hagenbach) are automatically treated like a phrase: the search looks for both parts directly next to each other.
What does not work¶
- Terms of fewer than 3 characters are ignored (
ag,zb). - Very frequent short words such as «und», «der», «die» are excluded from the database's search index (so-called stop words).
- Searching in the middle of a word is not possible (see above).
Distinction from the weighted search¶
The full-text search searches archival objects. The weighted search is a different function and concerns the list views of actors, places and keywords — there, hits are sorted by relevance.
