Video introduction (German): Suchfunktion
Full-text search
The global search works with the full-text search. With it, you search the content of courses, groups and learning resources for your search terms, for example in forum posts, wiki pages and in files from folders. The full-text search covers the file formats PDF, HTML, TXT, Word, PowerPoint and Excel. It does not index personal data such as profiles or visiting cards.
Important
Using the full-text search, you will only ever find the course content to which you have access.
Advanced search
If the full-text search returns too many hits, refine it with the advanced search. You open it in the dialog "Full-text search" with the link "Advanced search" below the search field.
The advanced search offers the fields Full-text search, Author, Title, Description, Creation date, Last modification, Document type, License and Meta data. The search fields are linked with the Boolean AND operator. If you fill in the fields "Title" and "Author", for example, the search only finds documents that contain both terms in the respective field.
Exception: The field "Full-text search" searches across all fields.
From the result list, you can jump directly to the learning content with the search term found.
Bulk search
If you are looking for many people at once, for example with a list of e-mail addresses from an Office document, switch to the bulk search. Some search forms offer the link "Bulk search" for this. Instead of the search form with individual input fields, a single large field then appears. Paste the values from the clipboard there, one per line, and click "Search". The link "Search form" takes you back.
Reset search
You remove a search term with one click, without clearing the field by hand. As soon as the search field contains something, a round button with a cross and the tooltip "Reset search" appears on the right in the field. A click on it clears the field.
What happens next depends on where the search field is:
- In tables, the table immediately shows the entries again without the restriction by the search term.
- In the large search field on the entry pages of Coaching and Course Planner, the click only clears the field. A new search only starts when you click "Search" again or press the Enter key.
- In the large search field of the Catalog, the click also only clears the field as long as no search has run yet. If search results are already shown below it, the Catalog immediately shows the offers again without the restriction by the search term.
Search syntax
With the following syntax, you narrow down your search query.
Individual terms, e.g. OpenOlat
Multiple terms in the search field are always linked with the OR operator.
Search using wildcards: To search for specific word fragments, use wildcards.
- The question mark in a search term stands for any single letter. For example, by entering te?t you will find all documents containing the words "test", "text" etc.
- The asterisk in a search term stands for any number of letters. For example, if you enter the search term Test_, you will find all documents containing words beginning with "Test". The asterisk can also appear within a search term: _Tet
Advanced search: In the advanced search, the various search fields are linked with the AND operator.
Metadata
Metadata helps you recognize a document and find it in the search. Metadata or meta information is data that contains information about the characteristics of other data, but not the data itself. It describes a file with additional information such as a title, the author or the publisher. This makes it easier to recognize what kind of document it is. This is particularly useful if the title of a document does not fit into the file name because it is too long or contains special characters.
You can add metadata to each file and also to complete learning resources. The metadata is optional and does not have to be filled in. It is based on the Dublin Core Simple Standard. Some metadata cannot be changed: the name of the person who uploaded the document, the size of the document, the time at which the document was uploaded and the file type. You can enter information such as the original author, the title, a description, the source or the language manually.
The full-text search indexes the metadata. You therefore also find documents via the terms in their metadata.
Lock file: In the metadata of a file, select the option "Locked" in the field "Locked" so that other users can neither overwrite, delete nor move the file. Locked files show a lock in the file list. This option does not exist for folders.
The field "External link to this resource" in the metadata shows a link with which you can also link directly to the file from outside OpenOlat.
