list=prefixsearch (ps)
- This module requires read rights.
- This module can be used as a generator.
- Source: MediaWiki
- License: GPL-2.0-or-later
Perform a prefix search for page titles.
Despite the similarity in names, this module is not intended to be equivalent to Special:PrefixIndex; for that, see action=query&list=allpages with the apprefix parameter. The purpose of this module is similar to action=opensearch: to take user input and provide the best-matching titles. Depending on the search engine backend, this might include typo correction, redirect avoidance, or other heuristics.
Parameters:
- pssearch
Search string.
- This parameter is required.
- psnamespace
Namespaces to search. Ignored if pssearch begins with a valid namespace prefix.
- Values (separate with | or alternative): 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 828, 829, 2300, 2301, 2302, 2303
- To specify all values, use *.
- Default: 0
- pslimit
Maximum number of results to return.
- No more than 500 (5,000 for bots) allowed.
- Type: integer or max
- Default: 10
- psoffset
When more results are available, use this to continue.
- Type: integer
- Default: 0
Example:
- Search for page titles beginning with meaning.
- api.php?action=query&list=prefixsearch&pssearch=meaning [open in sandbox]
