Phrase Searching

COBISS+ allows for phrase searching with the use of " ".

The query:

Searching Specific Fields

The single search box will search across many fields automatically. For example, entering an ISBN or ISSN will bring back associated records.

You can explicitly search a field using the syntax: field:(query).

  • Title

Boolean Operators

COBISS+ offers the following Boolean operations: AND, OR and NOT. The operators must be written in ALL CAPS.

By default, all terms in a search are combined with the AND operator. To expand the results set, use the OR operator.

For example:

microcircuits OR nanocircuits

will return items that contain either term.

This can be combined with quoted terms such as:

"teacher education" OR "educator training"

To exclude items in Summon™, use the NOT operator or - character before a term.

When used in the following query:

animal NOT dog

the results will not include the term dog.

Wildcard Use

Searches within COBISS+ can be performed using the wildcards ? and *.

The question mark (?) will match any one character and can be used to find Olsen or Olson by searching for


The asterisk (*) will match zero or more characters within a word or at the end of a word.

A search for:


would match Charter, Character and Chapter.

When used at the end of a word, such as:


it will match all suffixes Temptation, Temple and Temporary.

Wildcards cannot be used as the first character of a search.
