35===== DokuWiki Sphinx Search plugin features=====
36
37To 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:
38
39=== Phrase search (\"\") ===
40Put double quotes around a set of words to enable phrase search mode. For example:
41<code>\"James Bond\"</code>
42
43=== Search within a namespace ===
44You can add \"@ns\" parameter to limit the search to some namespace. For exapmle:
45<code>hotel @ns personal:mike:travel</code>
46Such query will return only results from \"personal:mike:travel\" namespace for keyword \"hotel\".
47
48=== Excluding keywords or namespaces from search ===
49You can add a minus sign to a keyword or a category name exclude it from search. For example:
50<code>hotel @ns -personal:mike</code>
51Such query will look for \"hotel\" everywhere except the \"personal:mike\" namespace.
52<code>blog -post</code>
53Such query will look for documents that have keyword \"blog\" but don't have keyword \"post\".
