;; Swish-e and Swish++ backends by:
;; Christoph Conrad <christoph.conrad@gmx.de>.
;; IMAP backend by: Simon Josefsson <jas@pdc.kth.se>.
;;; Commentary:
-;; TODO: Documentation in the Gnus manual
-
-;; Where in the existing gnus manual would this fit best?
-
;; What does it do? Well, it allows you to search your mail using
;; some search engine (imap, namazu, swish-e, gmane and others -- see
;; later) by typing `G G' in the Group buffer. You will then get a
;; other backend.
;; The interface between the two layers consists of the single
-;; function `nnir-run-query', which just selects the appropriate
-;; function for the search engine one is using. The input to
-;; `nnir-run-query' is a string, representing the query as input by
-;; the user. The output of `nnir-run-query' is supposed to be a
-;; vector, each element of which should in turn be a three-element
-;; vector. The first element should be full group name of the article,
-;; the second element should be the article number, and the third
-;; element should be the Retrieval Status Value (RSV) as returned from
-;; the search engine. An RSV is the score assigned to the document by
-;; the search engine. For Boolean search engines, the
-;; RSV is always 1000 (or 1 or 100, or whatever you like).
+;; function `nnir-run-query', which dispatches the search to the
+;; proper search function. The argument of `nnir-run-query' is an
+;; alist with two keys: 'nnir-query-spec and 'nnir-group-spec. The
+;; value for 'nnir-query-spec is an alist. The only required key/value
+;; pair is (query . "query") specifying the search string to pass to
+;; the query engine. Individual engines may have other elements. The
+;; value of 'nnir-group-spec is a list with the specification of the
+;; groups/servers to search. The format of the 'nnir-group-spec is
+;; (("server1" ("group11" "group12")) ("server2" ("group21"
+;; "group22"))). If any of the group lists is absent then all groups
+;; on that server are searched.
+
+;; The output of `nnir-run-query' is supposed to be a vector, each
+;; element of which should in turn be a three-element vector. The
+;; first element should be full group name of the article, the second
+;; element should be the article number, and the third element should
+;; be the Retrieval Status Value (RSV) as returned from the search
+;; engine. An RSV is the score assigned to the document by the search
+;; engine. For Boolean search engines, the RSV is always 1000 (or 1
+;; or 100, or whatever you like).
;; The sorting order of the articles in the summary buffer created by
;; nnir is based on the order of the articles in the above mentioned
;; `nnir-engines'. Then, users can choose the backend by setting
;; `nnir-search-engine' as a server variable.
