% Search Syntax

This only applies to built-in search, plugins like sphinx_search may override this syntax.

Search query consists of several keywords. Keyword starting with "-" is considered a negative match. Several special keywords are available:

@{date} - match by date. For example, @yesterday or @2011-11-03. Please note that due to incomplete implementation, special date keywords like yesterday might not match all articles if user timezone is different from tt-rss internal timezone (UTC).
pub:{true,false} - match only published or unpublished articles
star:{true, false} - same, starred articles
unread:{true, false} - self explanatory (requires trunk as of 05.03.2015)
note:{true, false, sometext} - same, for articles having an attached note or matching the specified text
label:Somelabel - articles that belong to a specified label
title:, author: - self explanatory

Pointless as it may be, you can combine the negative prefix with the special keywords: -star:true would essentially mean star:false.
