You want to perform a full-text search with search operators in d.velop documents. The search is case insensitive. You therefore get the same search results, regardless of whether you write in uppercase or lowercase letters.
The full-text search follows the Elasticsearch simple query string syntax. You can find more information on the Elasticsearch website.
You can use the following search operators for your search:
+ (plus sign): This is used for AND operators.
Space character (white space): Behaves in the same way as the plus sign.
| (vertical line): This is used for OR operators, and is also called the pipe symbol.
- (minus sign): Excludes units (that is, words or numbers).
" (quotation mark): This is used to search for a specific sequence of units.
* (asterisk): This is used as a wildcard at the end of the word.
( ) (brackets): Groups units and indicates logical priority.
\ (backslash): Suppresses the function of other search operators.
The logical AND is used as the standard link operator. That means that individual search terms without a search operator are always linked with a logical AND.
