一個Common Lisp客戶端用于與 elasticsearch交互。

Fetching a document

Asks the server for a document. If none exists, it still returns an empty document, but a warning is signalled:

(document-by-id *my-documents* "1")

;; => #<<DOCUMENT> /highway/whatever/1 {10083980C3}>

(handler-case (document-by-id *my-documents* "no-such-doc")
  (document-not-found "Sorry, I couldn't find that document"))

;; => "Sorry, I couldn't find that document"

Searching

The query language will be accessible with native Lisp syntax:

(get* *my-documents*
      (new-search (match "adventure" "_all")))

;; => (#<<DOCUMENT> /highway/whatever/321 {10071F58E3}>
;;     #<<DOCUMENT> /highway/whatever/412 {10071F5963}>
;;     #<<DOCUMENT> /highway/whatever/431 {10071F59E3}>)
;;    (:NUM-HITS 3 :SHARDS (:TOTAL 5 :FAILED 5 :SUCCESSFUL 0) 
;;     :TIMED-OUT NIL :TOOK 3)
