To use the search you need to just enter your search keywords into the searchbox at the top right corner of the DokuWiki. When basic simple search is not enough you can try using the methods listed below:
Put double quotes around a set of words to enable phrase search mode. For example:
You can add "@ns" parameter to limit the search to some namespace. For exapmle:
hotel @ns personal:mike:travel
Such query will return only results from "personal:mike:travel" namespace for keyword "hotel".
You can add a minus sign to a keyword or a category name exclude it from search. For example:
hotel @ns -personal:mike
Such query will look for "hotel" everywhere except the "personal:mike" namespace.
Such query will look for documents that have keyword "blog" but don't have keyword "post".
