The keywords are allowed to have multiple occurrence within the query at any place. The subqueries with the same keyword form the logical subquery, which returns the union of bugs of every subquery it contains. The result of the QUERY is an intersection of results of all subqueries.

QUERY is a sequence of lists of keyword-value pairs where the values are strings or numbers, i.e. :KEYWORD \"VALUE\" [:KEYWORD VALUE]* Every sublist of the QUERY forms a hyperestraier condition. A detailed description of hyperestraier conditions can be found at URL `http://fallabs.com/hyperestraier/uguide-en.html#searchcond'. The following conditions are possible: \[:phrase SEARCH-PHRASE :skip NUMBER :max NUMBER\] The string SEARCH-PHRASE forms the search on the database. It contains words to be searched for, combined by operators like AND, ANDNOT and OR. If there is no operator between the words, AND is used by default. The phrase keyword and value can also be omitted, this is useful in combination with other conditions. :skip and :max are optional. They specify, how many hits are skipped, and how many maximal hits are returned. This can be used for paged results. Per default, :skip is 0 and all possible hits are returned. There must be exactly one such condition. \[ATTRIBUTE VALUE+ :operation OPERATION :order ORDER\] ATTRIBUTE is one of the following keywords: :status -- Status of bug. Valid values are \"done\", \"forwarded\" and \"open\". :subject, :@title -- The subject of a message or the title of the bug, a string. :date, :@cdate -- The submission or modification dates of a message, a number. :submitter, :@author -- The email address of the submitter of a bug or the author of a message belonging to this bug, a string. The special email address \"me\" is used as pattern, replaced with `user-mail-address'. :package -- The value is the name of the package a bug belongs to, like \"emacs\", \"coreutils\", \"gnus\", or \"tramp\". :tags -- An arbitrary string the bug is annotated with. :severity -- This is the severity of the bug. The exact set of allowed values depends on the Debbugs port. Examples are \"normal\", \"minor\", \"wishlist\" etc. :operator defines the comparison operator to be applied to ATTRIBUTE. For string attributes this could be \"STREQ\" \(is equal to the string), \"STRNE\" \(is not equal to the string), \"STRINC\" \(includes the string), \"STRBW\" \(begins with the string), \"STREW\" \(ends with the string), \"STRAND\" \(includes all tokens in the string), \"STROR\" \(includes at least one token in the string), \"STROREQ\" \(is equal to at least one token in the string) or \"STRRX\" \(matches regular expressions of the string). For operators with tokens, several values for ATTRIBUTE shall be used. Numbers can be compared by the operators \"NUMEQ\" \(is equal to the number), \"NUMNE\" \(is not equal to the number), \"NUMGT\" \(is greater than the number), \"NUMGE\" \(is greater than or equal to the number), \"NUMLT\" \(is less than the number), \"NUMLE\" \(is less than or equal to the number) or \"NUMBT\" \(is between the two numbers). In the last case, there must be two values for ATTRIBUTE. If an operator is leaded by \"!\", the meaning is inverted. If a string operator is leaded by \"I\", the case of the value is ignored. The optional :order can be specified only in one condition. It means, that ATTRIBUTE is used for sorting the results. The following order operators exist: \"STRA\" \(ascending by string), \"STRD\" \(descending by string), \"NUMA\" \(ascending by number) or \"NUMD\" \(descending by number). A special case is an :order, where there is no corresponding attribute value and no operator. In this case, ATTRIBUTE is not used for the search. The result of the QUERY is a list of association lists with the same attributes as in the conditions. Additional attributes are `id': The bug number. `msg_num': The number of the message inside the bug log. `snippet': The surrounding text found by the search. For the syntax of the snippet, consult the hyperestraier user guide.
