Search terms get stemmed: E.g. 'Mining' will also find 'mine', 'mines' and 'miner'.
If you search for more than one word, only entries that contain all of the given words will be returned.
Words surrounded by parentheses will find exact matches:
E.g. "main page" will find all wiki articles with this name or the content contains 'main page'
Words preceding with a minus will be excluded: E.g. searching for 'tribe -barbarian'
will find all forum posts containing 'tribe' but exclude all forum posts containing 'barbarian'.
The start date won't be considered when searching the encyclopedia, maps or the wiki.
The default is set to return results for the span of one year.
