For example, the string `syntax` will search for all zettel containing the word “syntax”. If you want to search for all zettel with a title containing the word “syntax”, you must specify `title:syntax`. “title” denotes the [metadata key](00001006010000), in this case the [supported metadata key “title”](00001006020000#title). The colon character (“`:`”) is a [search operator](00001007705000), in this example to specify a match. “syntax” is the [search value](00001007706000) that must match to the value of the given metadata key, here “title”. A search expression may contain more than one search term, such as `title:syntax`. Search terms must be separated by one or more space characters, for example `title:syntax title:search`. All terms of a select expression must be true so that a zettel is selected. Above sequence of search expressions may be combined by specifying the keyword `OR`. At most one of those sequences must be true so that a zettel is selected. * [Search term](00001007702000) * [Search operator](00001007705000) * [Search value](00001007706000)
